The VDATranslator component is optimized for VDA translation, providing a simple way to convert VDA documents to and from XML or JSON.

Syntax

TeditranslatorVDATranslator

Remarks

The component provides a way to convert VDA to XML or JSON and vice versa.

Getting Started

The component will convert a document from the format specified by InputFormat to the format specified by OutputFormat. In practice this allows for converting to XML or JSON from EDI and vice versa.

Before translating from EDI to XML or JSON it is recommended to load a schema using the LoadSchema method. This ensures additional information can be included in the XML or JSON document. If a schema is specified the XML or JSON will include types and descriptions as element attributes which are useful for interpreting the data.

EDI elements may optionally be renamed when creating XML. To define how an element is renamed add a renaming rule by calling AddRenamingRule.

After calling Translate the resulting output will contain the EDI, XML or JSON data as defined by OutputFormat. If the output data is XML the ExportXMLSchema method may be called to export a schema (.xsd) defining the structure of a valid XML document. XML documents which adhere to this document may be translated from XML to EDI.

Input and Output Properties

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

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

• InputFile
• InputData

• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

<_1000 desc="Document/message name">TAX INVOICE</_1000>
</C002>

Where the elements "_1001", "C002", etc. are taken from the Id values of the EDI elements in the schema files.

Note: In order to produce valid XML, elements that would begin with a digit are prefixed with the "_" character.

In contrast if False (default) the XML generated may look like:

<BGM type="Segment">
<BGM01 type="Composite" desc="DOCUMENT/MESSAGE NAME">
<BGM0101 desc="Document/message name, coded">380</BGM0101>

<BGM0104 desc="Document/message name">TAX INVOICE</BGM0104>
</BGM01>

Data Type

Boolean

AddRenamingRule Method (VDATranslator Component)

This method adds a renaming rule to define how an EDI element is renamed when translating to XML.

Syntax

void __fastcall AddRenamingRule(String Rule);

Remarks

This method adds a renaming rule. The rule defining how EDI elements are renamed when translating to XML. Renaming rules are optional.

The renaming rule defines how EDI elements are renamed when translating to XML or JSON. The format is:

ediname:xmlanme

Note: Renaming rules are not required when converting from XML or JSON to EDI.

Config Method (VDATranslator Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

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 (VDATranslator Component)

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

Syntax

String __fastcall 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:

ExportXMLSchema Method (VDATranslator Component)

Exports a XML schema.

Syntax

void __fastcall ExportXMLSchema(String SchemaFile);

Remarks

This method exports a XML schema describing the valid format of the XML document.

After translating a document from EDI to XML, this method may be called to export a schema (.xsd) describing the structure of a valid XML documents. XML documents which adhere to this document may be translated from XML to EDI.

This method is helpful if XML will be generated outside of the component and later converted to EDI by the component.

The SchemaFile parameter specifies the absolute or relative path to the file on disk.

GenerateAck Method (VDATranslator Component)

Generates an EDI acknowledgement.

Syntax

String __fastcall GenerateAck();

Remarks

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

LoadRenamingRules Method (VDATranslator Component)

Loads a set of renaming rules from file.

Syntax

void __fastcall LoadRenamingRules(String RuleFile);

Remarks

This method loads a set of renaming rules from a file on disk. The RenamingRuleCount will reflect the number of rules that were loaded. When loading a rule file all previously loaded rules will be replaced.

The RuleFile parameter specifies the absolute or relative path to the file on disk.

LoadSchema Method (VDATranslator Component)

Loads a schema file describing a Transaction Set.

Syntax

void __fastcall LoadSchema(String FileName);

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 raises an exception.

Reset Method (VDATranslator Component)

Resets the state of the control.

Syntax

void __fastcall Reset();

Remarks

Reset resets the state of the component. All properties will be set to their default values.

SaveRenamingRules Method (VDATranslator Component)

Saves the current renaming rule set to a file.

Syntax

void __fastcall SaveRenamingRules(String RuleFile);

Remarks

This method saves the current renaming rule set specified by RenamingRule, RenamingRuleIndex, and RenamingRuleCount to a file on disk. These rules may be reloaded at a later time by calling LoadRenamingRules.

The RuleFile parameter specifies the absolute or relative path to the file on disk.

Translate Method (VDATranslator Component)

Translates the specified data.

Syntax

void __fastcall Translate();

Remarks

This method translates the specified data.

The component will convert a document from the format specified by InputFormat to the format specified by OutputFormat. In practice this allows for converting to XML or JSON from EDI and vice versa.

Before translating from EDI to XML or JSON it is recommended to load a schema using the LoadSchema method. This ensures additional information can be included in the XML or JSON document. If a schema is specified the XML or JSON will include types and descriptions as element attributes which are useful for interpreting the data.

EDI elements may optionally be renamed when creating XML. To define how an element is renamed add a renaming rule by calling AddRenamingRule.

After calling Translate the resulting output will contain the EDI, XML or JSON data as defined by OutputFormat. If the output data is XML the ExportXMLSchema method may be called to export a schema (.xsd) defining the structure of a valid XML document. XML documents which adhere to this document may be translated from XML to EDI.

Input and Output Properties

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

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

• InputFile
• InputData

• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

EndFunctionalGroup Event (VDATranslator Component)

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

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  int Count;
  String FullSegment;
} TeditranslatorVDATranslatorEndFunctionalGroupEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorEndFunctionalGroupEvent)(System::TObject* Sender, TeditranslatorVDATranslatorEndFunctionalGroupEventParams *e);
__property TeditranslatorVDATranslatorEndFunctionalGroupEvent OnEndFunctionalGroup = { read=FOnEndFunctionalGroup, write=FOnEndFunctionalGroup };

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 (VDATranslator Component)

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

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  String FullSegment;
} TeditranslatorVDATranslatorEndInterchangeEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorEndInterchangeEvent)(System::TObject* Sender, TeditranslatorVDATranslatorEndInterchangeEventParams *e);
__property TeditranslatorVDATranslatorEndInterchangeEvent OnEndInterchange = { read=FOnEndInterchange, write=FOnEndInterchange };

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 (VDATranslator Component)

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

Syntax

typedef struct {
} TeditranslatorVDATranslatorEndLoopEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorEndLoopEvent)(System::TObject* Sender, TeditranslatorVDATranslatorEndLoopEventParams *e);
__property TeditranslatorVDATranslatorEndLoopEvent OnEndLoop = { read=FOnEndLoop, write=FOnEndLoop };

Remarks

The EndLoop event will fire after the last segment in a loop is read. Each EndLoop event is paired with one StartLoop event.

EndTransaction Event (VDATranslator Component)

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

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  int Count;
  String FullSegment;
} TeditranslatorVDATranslatorEndTransactionEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorEndTransactionEvent)(System::TObject* Sender, TeditranslatorVDATranslatorEndTransactionEventParams *e);
__property TeditranslatorVDATranslatorEndTransactionEvent OnEndTransaction = { read=FOnEndTransaction, write=FOnEndTransaction };

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 (VDATranslator Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TeditranslatorVDATranslatorErrorEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorErrorEvent)(System::TObject* Sender, TeditranslatorVDATranslatorErrorEventParams *e);
__property TeditranslatorVDATranslatorErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

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 (VDATranslator Component)

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

Syntax

typedef struct {
  String TransactionCode;
  String StandardVersion;
} TeditranslatorVDATranslatorResolveSchemaEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorResolveSchemaEvent)(System::TObject* Sender, TeditranslatorVDATranslatorResolveSchemaEventParams *e);
__property TeditranslatorVDATranslatorResolveSchemaEvent OnResolveSchema = { read=FOnResolveSchema, write=FOnResolveSchema };

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.

Segment Event (VDATranslator Component)

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

Syntax

typedef struct {
  String Tag;
  String Name;
  String LoopName;
  String FullSegment;
} TeditranslatorVDATranslatorSegmentEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorSegmentEvent)(System::TObject* Sender, TeditranslatorVDATranslatorSegmentEventParams *e);
__property TeditranslatorVDATranslatorSegmentEvent OnSegment = { read=FOnSegment, write=FOnSegment };

Remarks

The Segment event will fire when a data segment is read. The Tag parameter contains the tag of the segment. Name contains the name of the segment as defined in the associated transaction set schema. LoopName contains the name of the loop or group this segment is present in (such as N1Loop1).

StartFunctionalGroup Event (VDATranslator Component)

Fires whenever a control segment is read that marks the start of a functional group.

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  String FullSegment;
} TeditranslatorVDATranslatorStartFunctionalGroupEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorStartFunctionalGroupEvent)(System::TObject* Sender, TeditranslatorVDATranslatorStartFunctionalGroupEventParams *e);
__property TeditranslatorVDATranslatorStartFunctionalGroupEvent OnStartFunctionalGroup = { read=FOnStartFunctionalGroup, write=FOnStartFunctionalGroup };

Remarks

The StartFunctionalGroup event will fire when a control segment marking the start of a functional group structure is read. The Tag parameter contains the tag of the segment, such as GS. ControlNumber contains the control number associated with the segment.

StartInterchange Event (VDATranslator Component)

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

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  String FullSegment;
} TeditranslatorVDATranslatorStartInterchangeEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorStartInterchangeEvent)(System::TObject* Sender, TeditranslatorVDATranslatorStartInterchangeEventParams *e);
__property TeditranslatorVDATranslatorStartInterchangeEvent OnStartInterchange = { read=FOnStartInterchange, write=FOnStartInterchange };

Remarks

The StartInterchange event will fire when a control segment marking the start of an interchange structure is read. The Tag parameter contains the tag of the segment, such as ISA. ControlNumber contains the control number associated with the segment.

StartLoop Event (VDATranslator Component)

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

Syntax

typedef struct {
  String Name;
} TeditranslatorVDATranslatorStartLoopEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorStartLoopEvent)(System::TObject* Sender, TeditranslatorVDATranslatorStartLoopEventParams *e);
__property TeditranslatorVDATranslatorStartLoopEvent OnStartLoop = { read=FOnStartLoop, write=FOnStartLoop };

Remarks

The StartLoop event will fire when the tag of a loop trigger segment is read. The Name parameter contains the schema-provided name of the loop, such as "N1Loop1".

StartTransaction Event (VDATranslator Component)

Fires whenever a control segment is read that marks the start of a transaction.

Syntax

typedef struct {
  String Tag;
  String ControlNumber;
  String Code;
  String FullSegment;
} TeditranslatorVDATranslatorStartTransactionEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorStartTransactionEvent)(System::TObject* Sender, TeditranslatorVDATranslatorStartTransactionEventParams *e);
__property TeditranslatorVDATranslatorStartTransactionEvent OnStartTransaction = { read=FOnStartTransaction, write=FOnStartTransaction };

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 (VDATranslator Component)

Fires whenever a validation warning is encountered.

Syntax

typedef struct {
  int WarnCode;
  String Message;
  int SegmentNumber;
  String SegmentTag;
  String TechnicalErrorCode;
  String SegmentErrorCode;
  String ElementErrorCode;
  int ElementPosition;
} TeditranslatorVDATranslatorWarningEventParams;
typedef void __fastcall (__closure *TeditranslatorVDATranslatorWarningEvent)(System::TObject* Sender, TeditranslatorVDATranslatorWarningEventParams *e);
__property TeditranslatorVDATranslatorWarningEvent OnWarning = { read=FOnWarning, write=FOnWarning };

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:

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:
