HL7Validator Class

Properties   Methods   Events   Config Settings   Errors  

HL7Validator is a lightweight EDI validation class designed for simple document validation.

Syntax

ipworksedi.Hl7validator

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); }

EDIStandardVersion Property (HL7Validator Class)

The version of the EDI specification.

Syntax

public String getEDIStandardVersion();

Default Value

""

Remarks

This property will be populated after parsing begins and the correct version string for is located via the schema, such as 004010 for X12.

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

InputData Property (HL7Validator Class)

The data to parse.

Syntax

public String getInputData();


public void setInputData(String inputData);

Default Value

""

Remarks

This property specifies the data to be parsed.

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:

• SetInputStream
• InputFile
• InputData

When a valid source is found the search stops.

InputFile Property (HL7Validator Class)

The file to parse.

Syntax

public String getInputFile();


public void setInputFile(String inputFile);

Default Value

""

Remarks

This property specifies the file to be processed. Set this property to the full or relative path to the file which will be processed.

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:

• SetInputStream
• InputFile
• InputData

When a valid source is found the search stops.

This property is not available at design time.

SchemaFormat Property (HL7Validator Class)

The format of the schema file.

Syntax

public int getSchemaFormat();


public void setSchemaFormat(int schemaFormat);


Enumerated values:
  public final static int schemaAutomatic = 0;
  public final static int schemaBinary = 1;
  public final static int schemaBizTalk = 2;
  public final static int schemaSEF = 3;
  public final static int schemaBOTS = 4;
  public final static int schemaAltova = 5;
  public final static int schemaJSON = 6;

Default Value

0

Remarks

Set SchemaFormat before calling the LoadSchema method to specify the loading schema format.

The following schema formats are supported:

ValidationErrors Property (HL7Validator Class)

Collection of validation errors for the current document.

Syntax

public ValidationErrorDetailList getValidationErrors();

Remarks

After calling Validate this property contains details of any validation errors. Validation errors are also accessible through the ValidationError event as the document is validated.

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 (Hl7validator Class)

Compiles an existing XSD schema into an optimized binary representation.

Syntax

public void compileSchema(String xsdSchema, String binSchema);

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 (Hl7validator Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

DisplaySchemaInfo Method (Hl7validator Class)

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

Syntax

public String 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:

If the schema file does not exist or cannot be parsed as an EDI schema, the class throws an exception.

LoadSchemaStream Method (Hl7validator Class)

Loads a schema stream describing a Transaction Set.

Syntax

public void loadSchemaStream(java.io.InputStream schemaStream);

Remarks

Parses Stream and loads it into an internal schema list. The SchemaFormat property must be set before calling this method.

The following SchemaFormat values are supported when calling this method:

• schemaBinary
• schemaBizTalk
• schemaSEF

All other schema formats are unsupported when using this method. LoadSchema may be used if an unsupported schema format is required.

Reset Method (Hl7validator Class)

Resets the parser.

Syntax

public void 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.

SetInputStream Method (Hl7validator Class)

Sets the stream from which the class will read the data to parse.

Syntax

public void setInputStream(java.io.InputStream inputStream);

Remarks

This method sets the stream from which the class will read the data to parse.

Input Properties

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

• SetInputStream
• InputFile
• InputData

When a valid source is found the search stops.

Validate Method (Hl7validator Class)

Validates the specified EDI document.

Syntax

public void validate();

Remarks

This method validates the EDI document specified by InputFile, SetInputStream or InputData.

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); }
