TRADACOMSReader Component

Properties Methods Events Config Settings Errors

The TRADACOMSReader component is optimized for TRADACOMS documents, providing a simple way to parse TRADACOMS documents.

Syntax

nsoftware.IPWorksEDITranslator.Tradacomsreader

Remarks

The component allows you to parse an incoming EDI document. This component works in two states, loading an entire document at once, or streaming portions of the document. These states are controlled by the BuildDOM property. By default BuildDOM is set to bdEntireDocument which parses the entire document at once, allowing you to use the XPath property to navigate the document.

To save memory for larger documents, you can choose to parse only sections of the document, instead of the entire document. When BuildDOM is set to per interchange (bdInterchange ) or per transaction (bdTransaction), the respective section of the document will be available for use with XPath from within the corresponding Start and End events. Finally, you may choose to set BuildDOM to bdNone, which means no DOM will be built and all data will be available only through events, but also will use very little memory. Below are example steps to parse an entire document:

First, use LoadSchema to load a schema file into the component. (Only necessary when preserving document structure).
Open an EDI document or stream by setting input via SetInputStream, InputFile or InputData and calling Parse.
If BuildDOM is set to bdEntireDocument, the events of the component will fire as the document is parsed, and XPath may be set to access any part of the document.
If bdInterchange or bdTransaction are specified, Parse is called the entire document will be parsed, with only the specified section being saved in memory at any given time. This means if you wish to set XPath to navigate within the section of the document, you will need to do so within the events of the component to prevent further processing of the document while you access the section. When parsing is completely, only the most recently parsed section will be available for use with XPath

If bdNone is specified, then all document information must be obtained through the events fired during parsing.

During parsing, the component performs basic validation of the incoming document. If validation fails, a warning is generated (fired as an event).

The XPath navigation is done through the XPath property. For example: EDIReader.XPath = "/IX[1]/FG[1]/TX[2]/N1Loop1[1]/N1[1]"; This example path means the following: Select the first N1 segment within the first iteration of the N1Loop1, within second transaction in the first functional group and interchange.

You can also make use of XPath conditional statements to locate the first element which matches a name=value. For example, you could use the following XPath to locate the path of the first element within any N1Loop1 that has a name=N101 and value=BT: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[N101='BT']";

Note that the conditional statements will search the children, but not the grand children of the element on which the conditional statement is applied. For instance in the above example the children of N1Loop1 will be searched, but the grandchildren will not.

Additionally if the schema loaded is a ArcESB JSON schema the element Id (from the schema) can be used in the conditional statement. For instance instead of N101 the following is also acceptable: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[98='BT']";

To display the structure of the parsed document use DisplaySchemaInfo. This is helpful when deciding how to navigate the document.

BuildDOM Property (TRADACOMSReader Component)

When True, an internal object model of the EDI document is created.

public TradacomsreaderBuildDOMs BuildDOM { get; set; }

enum TradacomsreaderBuildDOMs {
  bdEntireDocument,
  bdInterchange,
  bdTransaction,
  bdNone
}

Public Property BuildDOM As TradacomsreaderBuildDOMs

Enum TradacomsreaderBuildDOMs
  bdEntireDocument
  bdInterchange
  bdTransaction
  bdNone
End Enum

Default Value

Remarks

Set BuildDOM to bdEntireDocument (0) when you need to browse the current document through XPath.

Use bdInterchange (1) when parsing large documents to tell the component to only hold an internal object model of the current Interchange being parsed. When this value is used, and a new Interchange is encountered during parsing, the old interchange is cleared from memory. If the input contains a single Interchange, this is equivalent to using bdEntireDocument.

Use bdTransaction (2) when parsing large documents to tell the component to only hold an internal object model of the current transaction being parsed. When this value is used, and a new transaction is encountered during parsing, the old transaction is cleared from memory.

A value of bdNone (3) will tell the component to not save any internal state of the document being parsed, and thus XPath will be unavailable.

CompileSchema Method (TRADACOMSReader Component)

Compiles an existing XSD schema into an optimized binary representation.

Syntax

C#
VB.NET

public void CompileSchema(string xsdSchema, string binSchema);

Async Version
public async Task CompileSchema(string xsdSchema, string binSchema);
public async Task CompileSchema(string xsdSchema, string binSchema, CancellationToken cancellationToken);

Public Sub CompileSchema(ByVal XsdSchema As String, ByVal BinSchema As String)

Async Version
Public Sub CompileSchema(ByVal XsdSchema As String, ByVal BinSchema As String) As Task
Public Sub CompileSchema(ByVal XsdSchema As String, ByVal BinSchema As String, cancellationToken As CancellationToken) As Task

Remarks

This method parses XsdSchema and generates an optimized binary representation that is saved into the path referenced by BinSchema. Binary schemas are smaller and require less resources when loading later using LoadSchema

If the schema file does not exists or cannot be parsed as an EDI schema, the component throws an exception.

Config Method (TRADACOMSReader Component)

Sets or retrieves a configuration setting.

Syntax

C#
VB.NET

public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);

Public Function Config(ByVal ConfigurationString As String) As String

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DisplaySchemaInfo Method (TRADACOMSReader Component)

Returns a string showing the structure of the schema defining the document.

Syntax

C#
VB.NET

public string DisplaySchemaInfo();

Async Version
public async Task<string> DisplaySchemaInfo();
public async Task<string> DisplaySchemaInfo(CancellationToken cancellationToken);

Public Function DisplaySchemaInfo() As String

Async Version
Public Function DisplaySchemaInfo() As Task(Of String)
Public Function DisplaySchemaInfo(cancellationToken As CancellationToken) As Task(Of String)

Remarks

After calling LoadSchema this may be called to obtain information about the structure of the schema defining the document. If the desired XPath is not known this helps determine the structure so that the correct XPath can be built.

Note: A valid schema must be loaded via LoadSchema.

For instance: Console.WriteLine(component.DisplaySchemaInfo()); Will output text like:

DisplayXMLInfo Method (TRADACOMSReader Component)

Returns a string showing the structure of the parsed document as XML.

Syntax

C#
VB.NET

public string DisplayXMLInfo();

Async Version
public async Task<string> DisplayXMLInfo();
public async Task<string> DisplayXMLInfo(CancellationToken cancellationToken);

Public Function DisplayXMLInfo() As String

Async Version
Public Function DisplayXMLInfo() As Task(Of String)
Public Function DisplayXMLInfo(cancellationToken As CancellationToken) As Task(Of String)

Remarks

After the EDI document has been parsed this method may be called to obtain information about the document structure. The parsed data is represented as XML when queried. This shows all parsed data and may be useful for testing and debugging purposes. For instance: Console.WriteLine(component.DisplayXMLInfo()); Will output text like:

<IX tag="UNB" UNB1="UNOB:1" UNB2="WAYNE_TECH" UNB3="ACME" UNB4="160707:1547" UNB5="000000002" UNB6="" UNB7="1234" UNB8="" UNB9="" UNB10="" UNB11="1">

This method returns True if the xpath exists, False if not.

See XPath for details on the XPath syntax.

LoadSchema Method (TRADACOMSReader Component)

Loads a schema file describing a Transaction Set.

Syntax

C#
VB.NET

public void LoadSchema(string fileName);

Async Version
public async Task LoadSchema(string fileName);
public async Task LoadSchema(string fileName, CancellationToken cancellationToken);

Public Sub LoadSchema(ByVal FileName As String)

Async Version
Public Sub LoadSchema(ByVal FileName As String) As Task
Public Sub LoadSchema(ByVal FileName As String, cancellationToken As CancellationToken) As Task

Remarks

This method parses the File and loads it into an internal schema list. The component will attempt to automatically detect the SchemaFormat.

If the schema file does not exist or cannot be parsed as an EDI schema, the component throws an exception.

LoadSchemaStream Method (TRADACOMSReader Component)

Loads a schema stream describing a Transaction Set.

Syntax

C#
VB.NET

public void LoadSchemaStream(System.IO.Stream schemaStream);

Async Version
public async Task LoadSchemaStream(System.IO.Stream schemaStream);
public async Task LoadSchemaStream(System.IO.Stream schemaStream, CancellationToken cancellationToken);

Public Sub LoadSchemaStream(ByVal SchemaStream As System.IO.Stream)

Async Version
Public Sub LoadSchemaStream(ByVal SchemaStream As System.IO.Stream) As Task
Public Sub LoadSchemaStream(ByVal SchemaStream As System.IO.Stream, cancellationToken As CancellationToken) As Task

Remarks

Parses Stream and loads it into an internal schema list. The SchemaFormat property must be set before calling this method.

The following SchemaFormat values are supported when calling this method:

schemaBinary
schemaBizTalk
schemaSEF

All other schema formats are unsupported when using this method. LoadSchema may be used if an unsupported schema format is required.

Parse Method (TRADACOMSReader Component)

Parse the specified input data.

Syntax

C#
VB.NET

public void Parse();

Async Version
public async Task Parse();
public async Task Parse(CancellationToken cancellationToken);

Public Sub Parse()

Async Version
Public Sub Parse() As Task
Public Sub Parse(cancellationToken As CancellationToken) As Task

Remarks

This method parsed the input data specified by SetOutputStream, InputFile or InputData.

During parsing the following events may fire:

StartInterchange
StartFunctionalGroup
StartTransaction
Segment
StartLoop
EndLoop
EndTransaction
EndFunctionalGroup
EndInterchange

After Parse returns the document may be traversed by setting the XPath property. The XPath navigation is done through the XPath property. For example: EDIReader.XPath = "/IX[1]/FG[1]/TX[2]/N1Loop1[1]/N1[1]"; This example path means the following: Select the first N1 segment within the first iteration of the N1Loop1, within second transaction in the first functional group and interchange.

Input Properties

The component will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

SetInputStream
InputFile
InputData

When a valid source is found the search stops.

InputData Notes

When setting data to parse via InputData fragments or complete documents may be specified. To parse data in chunks set InputData and call Parse for each fragment.

When the parser is finally reset via the Reset method, all buffered text is flushed out through the ExtraData property.

Since the component can be used to parse EDI data fragments, the internal buffer will not be cleared until Reset is called. If you plan to use this method to parse multiple complete EDI documents be sure to call Reset between calls.

Reset Method (TRADACOMSReader Component)

Resets the parser.

Syntax

C#
VB.NET

public void Reset();

Async Version
public async Task Reset();
public async Task Reset(CancellationToken cancellationToken);

Public Sub Reset()

Async Version
Public Sub Reset() As Task
Public Sub Reset(cancellationToken As CancellationToken) As Task

Remarks

When called, the parser flushes all its buffers, firing events as necessary, and then initializes itself to its default state.

Reset must also be used as signal to the parser that the current stream of text has terminated.

SetInputStream Method (TRADACOMSReader Component)

Sets the stream from which the component will read the data to parse.

Syntax

C#
VB.NET

public void SetInputStream(System.IO.Stream inputStream);

Async Version
public async Task SetInputStream(System.IO.Stream inputStream);
public async Task SetInputStream(System.IO.Stream inputStream, CancellationToken cancellationToken);

Public Sub SetInputStream(ByVal InputStream As System.IO.Stream)

Async Version
Public Sub SetInputStream(ByVal InputStream As System.IO.Stream) As Task
Public Sub SetInputStream(ByVal InputStream As System.IO.Stream, cancellationToken As CancellationToken) As Task

Remarks

This method sets the stream from which the component will read the data to parse.

Input Properties

The component will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

SetInputStream
InputFile
InputData

When a valid source is found the search stops.

TryXPath Method (TRADACOMSReader Component)

Navigates to the specified XPath if it exists.

Syntax

C#
VB.NET

public bool TryXPath(string xpath);

Async Version
public async Task<bool> TryXPath(string xpath);
public async Task<bool> TryXPath(string xpath, CancellationToken cancellationToken);

Public Function TryXPath(ByVal xpath As String) As Boolean

Async Version
Public Function TryXPath(ByVal xpath As String) As Task(Of Boolean)
Public Function TryXPath(ByVal xpath As String, cancellationToken As CancellationToken) As Task(Of Boolean)

Remarks

This method will attempt to navigate to the specified XPath parameter if it exists within the document.

If the XPath exists the XPath property will be updated and this method returns True.

If the XPath does not exist the XPath property is not updated and this method returns False.

EndFunctionalGroup Event (TRADACOMSReader Component)

Fires whenever a control segment is read that marks the end of an interchange.

Syntax

C#
VB.NET

public event OnEndFunctionalGroupHandler OnEndFunctionalGroup;

public delegate void OnEndFunctionalGroupHandler(object sender, TradacomsreaderEndFunctionalGroupEventArgs e);

public class TradacomsreaderEndFunctionalGroupEventArgs : EventArgs {
  public string Tag { get; }
  public string ControlNumber { get; }
  public int Count { get; }
  public string FullSegment { get; }
}

Public Event OnEndFunctionalGroup As OnEndFunctionalGroupHandler

Public Delegate Sub OnEndFunctionalGroupHandler(sender As Object, e As TradacomsreaderEndFunctionalGroupEventArgs)

Public Class TradacomsreaderEndFunctionalGroupEventArgs Inherits EventArgs
  Public ReadOnly Property Tag As String
  Public ReadOnly Property ControlNumber As String
  Public ReadOnly Property Count As Integer
  Public ReadOnly Property FullSegment As String
End Class

Remarks

The EndFunctionalGroup event will fire when a control segment marking the end of a functional group is read. The Tag parameter contains the tag of the segment, such as GE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartFunctionalGroup event. Count contains the value of the count element included in the closing segment, which identifies the number of transactions in a functional group.

EndInterchange Event (TRADACOMSReader Component)

Fires whenever a control segment is read that marks the end of an interchange.

Syntax

C#
VB.NET

public event OnEndInterchangeHandler OnEndInterchange;

public delegate void OnEndInterchangeHandler(object sender, TradacomsreaderEndInterchangeEventArgs e);

public class TradacomsreaderEndInterchangeEventArgs : EventArgs {
  public string Tag { get; }
  public string ControlNumber { get; }
  public string FullSegment { get; }
}

Public Event OnEndInterchange As OnEndInterchangeHandler

Public Delegate Sub OnEndInterchangeHandler(sender As Object, e As TradacomsreaderEndInterchangeEventArgs)

Public Class TradacomsreaderEndInterchangeEventArgs Inherits EventArgs
  Public ReadOnly Property Tag As String
  Public ReadOnly Property ControlNumber As String
  Public ReadOnly Property FullSegment As String
End Class

Remarks

The EndInterchange event will fire when a control segment marking the end of an interchange is read. The Tag parameter contains the tag of the segment, such as IEA.

  Public ReadOnly Property SegmentErrorCode As String
  Public ReadOnly Property ElementErrorCode As String
  Public ReadOnly Property ElementPosition As Integer
End Class

Remarks

The Warning event will fire during parsing of a segment of an EDI document. The WarnCode parameter contains the type of warning encountered. Message is a textual description of the problem. SegmentNumber is the index of the segment where the problem was found.

SegmentTag holds the tag name of the segment. SegmentErrorCode holds the error code that may be used in the IK304 field of a 999. ElementErrorCode holds the error code that may be used in the IK403 field of a 999. ElementPosition is the position of the element where the error occurred.

It's very important to note that segment validation happens right in the middle of the parsing process. Because of this, the Warning event will usually fire long before the validated segment becomes the current segment for the parser state. This means you cannot access the parser properties to examine the current segment in relation with the Warning event when the event fires.

Possible WarnCode values are:


0	The component is not required but is present.
1	Invalid segment count.
2	Invalid transaction count.
3	Invalid group count.
4	Invalid interchange control number.
5	Invalid group control number.
6	Invalid transaction control number.
10	A required data element is missing.
11	Invalid field length.
12	Invalid field value.
13	A required component is missing.
14	The data element is not defined but is present.
30	Required segment is missing.
31	Required loop is missing.
32	Occurrences exceeds the schema defined limit.
33	Occurrences is less than the schema defined minimum.
40	Paired rule validation failed, the pair of elements must be present.
41	At least one of element is required, see message for list of elements.
42	Exclusion validation failed, only one of the elements can be present.
43	Conditional rule validation failed.
44	List conditional rule validation failed.
45	First then none validation failed. The presence of an element requires that other specific elements must not be present.
46	Only one or none of the elements can be present.

TechnicalErrorCode holds a technical error code that helps identify structural issues with the document. For instance when parsing an X12 document this will hold values that may be used for TA1 error codes. When parsing X12 documents the following codes are applicable:


001	The Interchange Control Numbers in the header ISA 13 and trailer IEA02 do not match.
014	Invalid interchange date value (non-numeric characters or wrong length).
015	Invalid interchange time value (non-numeric characters or wrong length).
022	The ISA segment is missing elements (invalid control structure).
024	Invalid interchange content (e.g., Invalid GS segment).

EDIElement Type

An Element within an EDI Segment.

Remarks

An EDI Segment contains one or more Elements. Elements can either be simple (they just contain a value) or they may be composite (containing more than one Component).

A simple element will simply contain a Value. For a composite element you must iterate over the components it contains by setting the ComponentIndex field, and then using the ComponentValue field to get the value at the corresponding index.

Fields

ComponentCount
int (read-only)
Default Value: 0

Number of components in the current element.

ComponentIndex
int
Default Value: 1

The index of the selected component of the current element. ComponentIndex valid values are from 0 to (ComponentCount - 1).

ComponentName
string (read-only)
Default Value: ""

The name of the component selected by ComponentIndex, according to the Transaction Set schema.

The name is based on the position of the element within the segment. For instance "DTM0101".

See ComponentSchemaName for additional details.

Note: This field is only applicable when a ArcESB JSON schema is loaded.

ComponentSchemaDesc
string (read-only)
Default Value: ""

The textual description of the component from the loaded ArcESB JSON schema.

This field holds a human readable description of the component as obtained from the ArcESB JSON schema.

Note: This field is only applicable when a ArcESB JSON schema is loaded.

ComponentSchemaName
string (read-only)
Default Value: ""

The name of the component as taken from the schema.

ComponentName holds positional (ref) value like "DTM0101". ComponentSchemaName holds the Id taken from the schema.

For instance: reader.XPath = "/IX/TX/DTM"; for (int i = 0; i < reader.XElements[0].ComponentCount; i++) { reader.XElements[0].ComponentIndex = i; Console.WriteLine(reader.XElements[i].ComponentSchemaName + ": " + reader.XElements[i].ComponentValue); }

When ComponentSchemaName is used this will use the name from the schema and will output values like:

2005: 137
2005: 137
2380: 201612151441

In contrast, if ComponentName was used the output would look like:

DTM0101: 137
DTM0101: 137
DTM0102: 201612151441

Note: This field is only applicable when a ArcESB JSON schema is loaded.

ComponentType

DT	DateTime
TM	Time
None	Type is unknown or not provided by the schema
Composite	This element has multiple components

Name
string (read-only)
Default Value: ""

The name of this EDI element, according to the Transaction Set schema. The name is based on the position of the element within the segment. For instance "N101".

See SchemaName for additional details.

Note: This field is only applicable when a ArcESB JSON schema is loaded.

RepeatCount
int (read-only)
Default Value: 1

The number of times this element is repeated in the in the segment. If the element is not repeated this will return 0.

To access the repeated element values set RepeatIndex.

RepeatIndex
int
Default Value: 1

The index of the selected instance of this repeatable element. RepeatIndex valid values are from 0 to (RepeatCount - 1).

Setting RepeatIndex will affect the value reported by all other properties.

SchemaDesc
string (read-only)
Default Value: ""

The textual description of the element from the loaded ArcESB JSON schema.

This field holds a human readable description of the element as obtained from the ArcESB JSON schema.

Note: This field is only applicable when a ArcESB JSON schema is loaded.

SchemaName
string (read-only)
Default Value: ""

The name of the element as taken from the schema.

Name holds positional (ref) value like "N101". SchemaName holds the Id taken from the schema.

For instance: reader.XPath = "/IX/FG/TX/N1Loop1[1]/N1"; for (int i = 0; i < reader.XElements.Count; i++) { Console.WriteLine(reader.XElements[i].SchemaName + ": " + reader.XElements[i].Value); }

When SchemaName is used this will use the name from the schema and will output values like:

98: ST
93: BUYSNACKS PORT
66: 9
67: 1223334445

In contrast, if Name was used the output would look like:

N101: ST
N102: BUYSNACKS PORT
N103: 9
N104: 1223334445

Note: This field is only applicable when a ArcESB JSON schema is loaded.

Value
string (read-only)
Default Value: ""

The value directly associated with this EDI element.

Note that this field will be populated with the entire element contents when a composite element exists. The components of the composite element will also be parsed out into the ComponentName, ComponentType, and ComponentValue fields.

Config Settings (TRADACOMSReader Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

TRADACOMSREADER Config Settings

CacheJSONSchemas: Whether to cache JSON schemas.

This setting specifies whether JSON schemas will be cached once parsed. If set to True the component will cache parsed data into an internal static variable which is accessible from other instances of the component.

This is useful in situations where separate instances of the component may be parsing similar data. Setting this to True can help reduce memory usage and increase parsing speed in situations where multiple component instances are being used at the same time with the same schema files. The default value is False.

When set to False the schema cache is cleared.

ClearSchemaCache: Clears the cached JSON schemas.

This setting may be queried to clear the cache of previously parsed JSON schemas. This is only applicable when CacheJSONSchemas is True. This is called in the following manner:

component.Config("ClearSchemaCache");

ComponentDelimiter: The delimiter separating components.

After parsing an EDI document, this configuration option will return the delimiter used to separate components within data elements of the EDI document.

This configuration option may be set in the StartInterchange event to specify the delimiter to be used.

CrossFieldValidationEnabled: Enables cross-field validation rules.

If true, cross-field validation rules present in the document schema will be checked. The default value is false. Note, Bots Schema Files do not support syntax rules, therefore CrossFieldValidation rules will never execute for these schemas.

EDIStandard: The document format.

This property specifies standard that the document follows. Possible values are:

1 (EDIFACT - default)
3 (TRADACOMS)

ElementDelimiter: The delimiter character separating data elements.

After parsing an EDI document, this configuration option will return the delimiter used to separate data elements within segments of the EDI document.

This configuration option may be set in the StartInterchange event to specify the delimiter to be used.

Encoding: The character encoding to be applied when reading and writing data.

If the data contains non-ASCII characters this setting should be specified so characters are properly preserved. This value should be set to a valid character set such as "UTF-8" or "ISO-8859-1".

HasXPath: Determines if the specified XPath exists.

This setting can be used to query if an XPath exists before setting XPath. For instance: Console.WriteLine(edireader.Config("HasXPath=IX/FG/TX/IT1Loop1/[2]"));

ReleaseChar: The character used to escape delimiters within values.

After parsing an EDI document, this configuration option will return the escape character used to escape delimiters within values within the EDI document.

This configuration option may be set in the StartInterchange event to specify the escape character to be used.

ResolveXPathOnSet: Determines whether or not the XPath is resolved when set.

When true, the component will fully resolve a detailed path when XPath is specified. In this case, the XPath property will contain the XSegment s name as well as the indices when queried after being set.

If this value is set to false, the exact string will be returned when the XPath property is queried from the last time it was set.

For example, the following code will print the string "/[1]/[1]/[1]/[10]" when this value is false, and would print "/IX[1]/FG[1]/TX[1]/IT1Loop1[4]" when this value is true: reader.XPath = "/[1]/[1]/[1]/[10]"; Console.WriteLine(reader.XPath);

In another example, the following code sample will print "IX/FG/TX/IT1Loop1" when false and would print "/IX[1]/FG[1]/TX[1]/IT1Loop1[1]" when true: reader.XPath = "IX/FG/TX/IT1Loop1"; Console.WriteLine(reader.XPath);

This is useful in cases where the full XPath including indices is needed for future processing.

SegmentDelimiter: The delimiter character separating segments within the EDI document.

After parsing an EDI document, this configuration option will return the delimiter used to separate segments within the EDI document.

This configuration option may be set in the StartInterchange event to specify the delimiter to be used.

StrictSchemaValidation: Specifies the behavior during schema validation.

This setting specifies what happens when performing schema validation and a validation warning occurs. By default this value is set to 1 (Warn) and the Warning event will fire, but processing will not stop. See the WarnCode parameter list in the Warning event for details about possible validation warnings. Possible values for this setting are:


0 (Ignore)	All validation warnings will be ignored. Warning will not fire with warnings.
1 (Warn - default)	The Warning event will fire with all validation warnings.
2 (Error)	All validation warnings are treated as errors and will cause an exception. Processing will stop immediately.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable: Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseFIPSCompliantAPI: Tells the component whether or not to use FIPS certified APIs.

When set to true, the component will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle FIPS, while all the other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting which applies to all instances of all components of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details please see the FIPS 140-2 Compliance article.

Note: This setting is only applicable on Windows.

Note: Enabling FIPS-compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to true.

Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all components used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
