EDIFACTReader Class

Properties Methods Events Config Settings Errors

The EDIFACTReader class is optimized for EDIFACT documents, providing a simple way to parse EDIFACT documents.

Syntax

EDIFACTReader

Remarks

The class allows you to parse an incoming EDI document. This class 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 class. (Only necessary when preserving document structure).
Open an EDI document or stream by setting input via InputFile or InputData and calling Parse.
If BuildDOM is set to bdEntireDocument, the events of the class 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 class 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 class 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 (EDIFACTReader Class)

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

Syntax

ANSI (Cross Platform)
int GetBuildDOM();
int SetBuildDOM(int iBuildDOM);

Unicode (Windows)
INT GetBuildDOM();
INT SetBuildDOM(INT iBuildDOM);

Possible Values

BD_ENTIRE_DOCUMENT(0), 
BD_INTERCHANGE(1), 
BD_TRANSACTION(2), 
BD_NONE(3)

int ipworkseditranslator_edifactreader_getbuilddom(void* lpObj);
int ipworkseditranslator_edifactreader_setbuilddom(void* lpObj, int iBuildDOM);

int GetBuildDOM();
int SetBuildDOM(int iBuildDOM);

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 class 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 class 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 class to not save any internal state of the document being parsed, and thus XPath will be unavailable.

TX	Refers to a Transaction Set node
'name'	The first segment or loop of the current container with the given schema name
name[i]	The i-th segment of the current container with the given schema-name
[i]	The i-th segment of the current container
[last()]	The last segment of the current container
[last()-i]	The segment located at the last location minus i in the current container
..	The parent of the current container

When XPath is set to a valid path, XSegment points to the name of the segment, with XTag, XSegmentType, and XChildren providing other properties of the segment. The elements of the current segment are provided in the XElements properties.

BuildDOM must be set to bdEntireDocument or bdTransaction prior to parsing the document for the XPath functionality to be available.

Example (Setting XPath)


Document root (Interchange)	`EDIReaderControl.XPath = "/"`
N1 segment in the first transaction	`EDIReaderControl.XPath = "/IX/FG/TX/N1Loop1/N1"`
3-th instance of the N2 segment	`EDIReaderControl.XPath = "/IX/FG/TX/N1Loop1/N2[3]"`

This property is read-only and not available at design time.

Data Type

Integer

XSegmentType Property (EDIFACTReader Class)

Indicates the current segment type.

Syntax

ANSI (Cross Platform)
int GetXSegmentType();

Unicode (Windows)
INT GetXSegmentType();

Possible Values

ST_NONE(0), 
ST_INTERCHANGE(1), 
ST_FUNCTIONAL_GROUP(2), 
ST_TRANSACTION(3), 
ST_INTERCHANGE_HEADER(4), 
ST_FUNCTIONAL_GROUP_HEADER(5), 
ST_TRANSACTION_HEADER(6), 
ST_TRANSACTION_SEGMENT(7), 
ST_TRANSACTION_LOOP(8), 
ST_TRANSACTION_FOOTER(9), 
ST_FUNCTIONAL_GROUP_FOOTER(10), 
ST_INTERCHANGE_FOOTER(11)

int ipworkseditranslator_edifactreader_getxsegmenttype(void* lpObj);

int GetXSegmentType();

Default Value

Remarks

The current segment will be a control segment footer/header or a transaction data segment.

This property is read-only and not available at design time.

Data Type

Integer

XTag Property (EDIFACTReader Class)

The tag of the current segment.

Syntax

ANSI (Cross Platform)
char* GetXTag();

Unicode (Windows)
LPWSTR GetXTag();

char* ipworkseditranslator_edifactreader_getxtag(void* lpObj);

QString GetXTag();

Default Value

Remarks

The current segment is specified via the XPath property.

This property is read-only and not available at design time.

Data Type

String

XTransactionCode Property (EDIFACTReader Class)

The transaction code of the current segment.

Syntax

ANSI (Cross Platform)
char* GetXTransactionCode();

Unicode (Windows)
LPWSTR GetXTransactionCode();

char* ipworkseditranslator_edifactreader_getxtransactioncode(void* lpObj);

QString GetXTransactionCode();

Default Value

Remarks

This property is read-only and not available at design time.

Data Type

String

CompileSchema Method (EDIFACTReader Class)

Compiles an existing XSD schema into an optimized binary representation.

Syntax

ANSI (Cross Platform)
int CompileSchema(const char* lpszXsdSchema, const char* lpszBinSchema);

Unicode (Windows)
INT CompileSchema(LPCWSTR lpszXsdSchema, LPCWSTR lpszBinSchema);

int ipworkseditranslator_edifactreader_compileschema(void* lpObj, const char* lpszXsdSchema, const char* lpszBinSchema);

int CompileSchema(const QString& qsXsdSchema, const QString& qsBinSchema);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (EDIFACTReader Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworkseditranslator_edifactreader_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DisplaySchemaInfo Method (EDIFACTReader Class)

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

Syntax

ANSI (Cross Platform)
char* DisplaySchemaInfo();

Unicode (Windows)
LPWSTR DisplaySchemaInfo();

char* ipworkseditranslator_edifactreader_displayschemainfo(void* lpObj);

QString DisplaySchemaInfo();

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:

Error Handling (C++)

Flush Method (EDIFACTReader Class)

Flushes the parser and checks its end state.

Syntax

ANSI (Cross Platform)
int Flush();

Unicode (Windows)
INT Flush();

int ipworkseditranslator_edifactreader_flush(void* lpObj);

int Flush();

Remarks

When Flush is called, the parser flushes all its buffers, firing events as necessary, and then checks its end state.

Any extra un-parsed data will be populated in the ExtraData property after this method is called.

Error Handling (C++)

GenerateAck Method (EDIFACTReader Class)

Generates an EDI acknowledgement.

Syntax

ANSI (Cross Platform)
char* GenerateAck();

Unicode (Windows)
LPWSTR GenerateAck();

char* ipworkseditranslator_edifactreader_generateack(void* lpObj);

QString GenerateAck();

Remarks

This functionality is not yet implemented and is reserved for future use.

Error Handling (C++)

HasXPath Method (EDIFACTReader Class)

Determines whether a specific element exists in the document.

Syntax

ANSI (Cross Platform)
int HasXPath(const char* lpszXPath);

Unicode (Windows)
INT HasXPath(LPCWSTR lpszXPath);

int ipworkseditranslator_edifactreader_hasxpath(void* lpObj, const char* lpszXPath);

bool HasXPath(const QString& qsXPath);

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it via XPath.

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

See XPath for details on the XPath syntax.

Error Handling (C++)

This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

LoadSchema Method (EDIFACTReader Class)

Loads a schema file describing a Transaction Set.

Syntax

ANSI (Cross Platform)
int LoadSchema(const char* lpszFileName);

Unicode (Windows)
INT LoadSchema(LPCWSTR lpszFileName);

int ipworkseditranslator_edifactreader_loadschema(void* lpObj, const char* lpszFileName);

int LoadSchema(const QString& qsFileName);

Remarks

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

If the schema file does not exist or cannot be parsed as an EDI schema, the class fails with an error.

Error Handling (C++)

Parse Method (EDIFACTReader Class)

Parse the specified input data.

Syntax

ANSI (Cross Platform)
int Parse();

Unicode (Windows)
INT Parse();

int ipworkseditranslator_edifactreader_parse(void* lpObj);

int Parse();

Remarks

This method parsed the input data specified by 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 class 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:

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 class 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.

Error Handling (C++)

Reset Method (EDIFACTReader Class)

Resets the parser.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworkseditranslator_edifactreader_reset(void* lpObj);

int Reset();

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.

Error Handling (C++)

TryXPath Method (EDIFACTReader Class)

Navigates to the specified XPath if it exists.

Syntax

ANSI (Cross Platform)
int TryXPath(const char* lpszxpath);

Unicode (Windows)
INT TryXPath(LPCWSTR lpszxpath);

int ipworkseditranslator_edifactreader_tryxpath(void* lpObj, const char* lpszxpath);

bool TryXPath(const QString& qsxpath);

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.

Error Handling (C++)

EndFunctionalGroup Event (EDIFACTReader Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireEndFunctionalGroup(EDIFACTReaderEndFunctionalGroupEventParams *e);

typedef struct {
  const char *Tag;
  const char *ControlNumber;

virtual int FireEndFunctionalGroup(EDIFACTReaderEndFunctionalGroupEventParams *e) {...}

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 (EDIFACTReader Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireEndInterchange(EDIFACTReaderEndInterchangeEventParams *e);

typedef struct {
  const char *Tag;
  const char *ControlNumber;

virtual int FireEndInterchange(EDIFACTReaderEndInterchangeEventParams *e) {...}

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. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartInterchange event.

EndLoop Event (EDIFACTReader Class)

Fires when the end of a loop is detected in a transaction set.

Syntax

ANSI (Cross Platform)
virtual int FireEndLoop(EDIFACTReaderEndLoopEventParams *e);

typedef struct {
  int reserved;
} EDIFACTReaderEndLoopEventParams;


Unicode (Windows)
virtual INT FireEndLoop(EDIFACTReaderEndLoopEventParams *e);

  const QString &FullSegment();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void EndTransaction(EDIFACTReaderEndTransactionEventParams *e);

// Or, subclass EDIFACTReader and override this emitter function.
virtual int FireEndTransaction(EDIFACTReaderEndTransactionEventParams *e) {...}

Remarks

The EndTransaction event will fire when a control segment marking the end of a transaction is read. The Tag parameter contains the tag of the segment, such as SE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartTransaction event. Count contains the value of the count element included in the closing segment, which identifies the number of segments in a transaction set.

Error Event (EDIFACTReader Class)

Fired when information is available about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(EDIFACTReaderErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} EDIFACTReaderErrorEventParams;


Unicode (Windows)

void Error(EDIFACTReaderErrorEventParams *e);

// Or, subclass EDIFACTReader and override this emitter function.
virtual int FireError(EDIFACTReaderErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

ResolveSchema Event (EDIFACTReader Class)

Fires whenever a new transaction set is encountered and no schema is found for it.

Syntax

ANSI (Cross Platform)
virtual int FireResolveSchema(EDIFACTReaderResolveSchemaEventParams *e);

typedef struct {
  const char *TransactionCode;
  const char *StandardVersion;
  int reserved;
} EDIFACTReaderResolveSchemaEventParams;


Unicode (Windows)
virtual INT FireResolveSchema(EDIFACTReaderResolveSchemaEventParams *e);

typedef struct {
  LPCWSTR TransactionCode;

  INT reserved;
} EDIFACTReaderResolveSchemaEventParams;

#define EID_EDIFACTREADER_RESOLVESCHEMA 6

virtual INT IPWORKSEDITRANSLATOR_CALL FireResolveSchema(LPSTR &lpszTransactionCode, LPSTR &lpszStandardVersion);

class EDIFACTReaderResolveSchemaEventParams {
public:
  const QString &TransactionCode();

  const QString &StandardVersion();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void ResolveSchema(EDIFACTReaderResolveSchemaEventParams *e);

// Or, subclass EDIFACTReader and override this emitter function.
virtual int FireResolveSchema(EDIFACTReaderResolveSchemaEventParams *e) {...}

Remarks

The ResolveSchema event will fire when a the class encounters the header segment of a new transaction set, but it finds no schema corresponding to it already loaded.

TransactionCode contains the code of the transaction, such as "810" or "APERAK".

StandardVersion contains the version of the transaction, such as "004010" or "D95A".

When processing this event, the caller can use LoadSchema() to load a new schema into the class that can be used to parse the transaction.

After the event fires, if the class still doesn't have a matching schema, then it will attempt schema-less parsing of the transaction set.

Segment Event (EDIFACTReader Class)

Fires whenever a data segment in a transaction set is read.

Syntax

ANSI (Cross Platform)
virtual int FireSegment(EDIFACTReaderSegmentEventParams *e);

Remarks

The StartTransaction event will fire when a control segment marking the start of a transaction is read. The Tag parameter contains the tag of the segment, such as ST. ControlNumber contains the control number associated with the segment. Code contains the transaction code (such as 810).

Warning Event (EDIFACTReader Class)

Fires whenever a validation warning is encountered.

void Warning(EDIFACTReaderWarningEventParams *e);

// Or, subclass EDIFACTReader and override this emitter function.
virtual int FireWarning(EDIFACTReaderWarningEventParams *e) {...}

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).

Config Settings (EDIFACTReader Class)

The class 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 class, access to these internal properties is provided through the Config method.

EDIRFACTREADER Config Settings

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 class 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.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class 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 classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents: Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

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

When set to true, the class 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 classes 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 class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class 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.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.

Trappable Errors (EDIFACTReader Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
