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 class depends largely on the schema's definition.

When the Validate method is called the class 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); }

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.

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 (IPWorksEDI_TRADACOMSValidator Class)

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

public function fireSegment($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 7, array($this, 'fireSegment'));

Parameter List

 'tag'
 'name'
 'loopname'
 'fullsegment'

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 (IPWorksEDI_TRADACOMSValidator Class)

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

Object Oriented Interface

public function fireStartFunctionalGroup($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 8, array($this, 'fireStartFunctionalGroup'));

Parameter List

 'tag'
 'controlnumber'
 'fullsegment'

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 (IPWorksEDI_TRADACOMSValidator Class)

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

Object Oriented Interface

public function fireStartInterchange($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 9, array($this, 'fireStartInterchange'));

Parameter List

 'tag'
 'controlnumber'
 'fullsegment'

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 (IPWorksEDI_TRADACOMSValidator Class)

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

Object Oriented Interface

public function fireStartLoop($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 10, array($this, 'fireStartLoop'));

Parameter List

 'name'

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 (IPWorksEDI_TRADACOMSValidator Class)

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

Object Oriented Interface

public function fireStartTransaction($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 11, array($this, 'fireStartTransaction'));

Parameter List

 'tag'
 'controlnumber'
 'code'
 'fullsegment'

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).

ValidationError Event (IPWorksEDI_TRADACOMSValidator Class)

Fires whenever a validation error is encountered.

Object Oriented Interface

public function fireValidationError($param);

Procedural Interface

ipworksedi_tradacomsvalidator_register_callback($res, 12, array($this, 'fireValidationError'));

Parameter List

 'errorcode'
 'message'
 'segmentnumber'
 'segmenttag'
 'technicalerrorcode'
 'segmenterrorcode'
 'elementerrorcode'
 'elementposition'
 'line'
 'column'

Remarks

This event will fire with errors as the EDI document is validated. The ErrorCode parameter contains the type of error 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. ElementPosition is the position of the element where the error occurred.

The Line and Column parameters identify the location within the EDI document where the error occurred.

Possible ErrorCode values are:

X12 Specific Parameters

The following parameters are available in all validator classes but are only applicable to X12 document validation at this time.

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.

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:

Config Settings (TRADACOMSValidator 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.
