X12Validator Component
Properties Methods Events Config Settings Errors
The X12Validator component validates X12 documents against the specified standard, ensuring compliance and correctness.
Syntax
TedX12Validator
Remarks
This component provides a simple way to validate an EDI document and obtain details about any validation errors.
Before calling Validate 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 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 = @"C:\X12_Files\810_InvalidRepeat.txt";
validator.LoadSchema(@"C:\X12_Schemas\4010.xml", "810");
validator.Validate();
foreach (X12ValidationErrorDetail error in validator.ValidationErrors) {
Console.WriteLine(error.ErrorCode + ": " + error.ErrorMessage);
}

Delimiters Property (X12Validator Component)
Contains the delimiters for the EDI Document.
Syntax
property Delimiters: TedX12Delimiters read get_Delimiters;
Remarks
This property contains the delimiters that will be used when parsing the X12 document. If the document uses delimiters other than the default, change the properties of this object to parse the document correctly.
This property is read-only and not available at design time.
Please refer to the X12Delimiters type for a complete list of fields.InputData Property (X12Validator Component)
The EDI message, specified as a string.
Syntax
property InputData: String read get_InputData write set_InputData;
Default Value
''
Remarks
Set this property to specify the input EDI message as a string. The message can then be parsed with Parse.
This property is not available at design time.
InputFile Property (X12Validator Component)
The file containing the EDI message.
Syntax
property InputFile: String read get_InputFile write set_InputFile;
Default Value
''
Remarks
Set this property to specify the input EDI message as a file. The message can then be parsed with Parse.
If the file is not found or cannot be opened, an error will be returned.
Note: If both InputFile and InputData are set, InputData takes precedence.
This property is not available at design time.
ValidationErrors Property (X12Validator Component)
Collection of validation errors for the current document.
Syntax
property ValidationErrors: TedX12ValidationErrorDetailList read get_ValidationErrors;
Remarks
After calling Validate this property contains details of any validation errors. Validation errors are also accessible through the ValidateWarning event as the document is validated.
This property is read-only and not available at design time.
Please refer to the X12ValidationErrorDetail type for a complete list of fields.Config Method (X12Validator Component)
Sets or retrieves a configuration setting.
Syntax
function Config(ConfigurationString: String): 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.
LoadSchema Method (X12Validator Component)
Loads schema information from a file or string data.
Syntax
procedure LoadSchema(fileOrData: String; messagename: String);
Remarks
This method loads schema information for use when parsing, validating, and translating messages.
The FileOrData parameter can be set to the path of a file containing schema data, or can be set to the contents of a schema file directly.
MessageName can be set to the name of a specific message to load only the specified message's schema information. If left empty or set to "*", the entire schema will be loaded.
Reset Method (X12Validator Component)
Resets all properties to their default values.
Syntax
procedure Reset();
Remarks
This method resets all properties of the component to their default values as specified in the property definitions.
Validate Method (X12Validator Component)
Validate the EDI document and warn about any errors encountered.
Syntax
procedure Validate();
Remarks
This method parses the input EDI document, firing the ValidateWarning event for any non-blocking errors it encounters.
Error Event (X12Validator Component)
Fires when a parsing error occurs.
Syntax
type TErrorEvent = procedure ( Sender: TObject; ErrorCode: Integer; const Description: String ) of Object;
property OnError: TErrorEvent read FOnError write FOnError;
Remarks
This event fires when the component encounters a parsing error while processing a document.
ResolveSchema Event (X12Validator Component)
Fires to request schema information for a specific transaction set.
Syntax
type TResolveSchemaEvent = procedure ( Sender: TObject; const VersionNumber: String; const TransactionSetIDCode: String ) of Object;
property OnResolveSchema: TResolveSchemaEvent read FOnResolveSchema write FOnResolveSchema;
Remarks
LoadSchema can be called from within this event to load the schema information for the specified transaction set.
ValidateWarning Event (X12Validator Component)
Fires to warn about validation errors.
Syntax
type TValidateWarningEvent = procedure ( Sender: TObject; Position: Int64; Line: Integer; Column: Integer; const ErrorCode: String; const ErrorMessage: String; ErrorType: Integer ) of Object;
property OnValidateWarning: TValidateWarningEvent read FOnValidateWarning write FOnValidateWarning;
Remarks
