VDAValidator Component

Properties   Methods   Events   Config Settings   Errors  

VDAValidator is a lightweight EDI validation component designed for simple document validation.

Syntax

nsoftware.IPWorksEDI.Vdavalidator

Remarks

This component provides a simple way to validate an EDI document and obtain details about any validation errors.

EDI Validation

Before calling Validate set SchemaFormat and call LoadSchema to load the schema for the document to be validated. The schema defines many validation rules such as minimum and maximum lengths, minimum and maximum occurrences, and more. The validation performed by the component depends largely on the schema's definition.

When the Validate method is called the component will attempt to validate the document. If errors are found during validation the ValidationError event will fire with details about each error as it is encountered. After the document has been validated the ValidationErrors property will be populated with details of each error.

Inspect the ValidationErrors property for information on any errors that were encountered.

Validation Example validator.InputFile = "files/EDIDocuments/MyEDIDoc.txt"; validator.LoadSchema("my_schemas/00501/RSSBus_005010X222A1_837.json"); validator.Validate(); foreach (ValidationErrorDetail error in validator.ValidationErrors) { Console.WriteLine(error.ErrorCode + ": " + error.Message); }

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

Please refer to the ValidationErrorDetail type for a complete list of fields.

CompileSchema Method (VDAValidator Component)

Compiles an existing XSD schema into an optimized binary representation.

Syntax

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 (VDAValidator Component)

Sets or retrieves a configuration setting.

Syntax

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 (VDAValidator Component)

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

Syntax

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:

  Public ReadOnly Property TransactionCode As String
  Public ReadOnly Property StandardVersion As String
End Class

Remarks

The ResolveSchema event will fire when a the component 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 component that can be used to parse the transaction.

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

Config Settings (VDAValidator 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.

X12Validator 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 (default), cross-field validation rules present in the document schema will be checked.

Note, Bots Schema Files do not support syntax rules, therefore CrossFieldValidation rules will never execute for these schemas.

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".

ExtraData:   Extra data that has not been parsed by the component.

This setting will only be populated after the Flush method has been called and data exists in the internal parser which has not been processed.

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]"));

ISA11IsRepetitionSeparator:   Specifies whether the ISA11 value is treated as a Repetition Separator or Standard Identifier.

By default this value is True and the ISA11 value is treated as a Repetition Separator in all documents with version 004040 or greater. Set this value to False to treat ISA11 as a Standard Identifier instead of a Repetition Separator.

MaxValidationErrors:   The maximum number of errors to save in the ValidationErrors property.

This setting specifies the maximum number of errors that will be kept in the ValidationErrors property. Once this limit is exceeded the ValidationError event will continue to fire but details will not be saved in the ValidationErrors property. The default value is 200.

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.
