Package net.ionite.docval.validation.validator

Class XSLTValidator

java.lang.Object

net.ionite.docval.validation.validator.XSLTValidator

All Implemented Interfaces:

DocumentValidator

Direct Known Subclasses:

SCHValidator

public class XSLTValidator
extends Object
implements DocumentValidator

This class implements the DocumentValidor interface for Schematron- XSLT validation files. These are XSLT files that transform an input document to a document following the SVRL schema, and are generally distributed as the 'compiled' version of schematron files. Using these files is much faster than using .SCH files with the SCHValidator directly.

Field Summary

Fields

protected InputStream	_stream	The InputStream containing the XSLT created from a schematron definition, if this validator is initialized with an inputstream.
protected org.slf4j.Logger	logger	General Logger instance

Constructor Detail

XSLTValidator

public XSLTValidator(String filename)

Construct an Schematron XSLT Validator with the given XSLT file.

Parameters:

filename - The XSLT file created from a schematron definition

XSLTValidator

public XSLTValidator(InputStream stream)

Construct an Schematron XSLT Validator with the given input stream

Parameters:

stream - the InputStream containing the XSLT created from a schematron definition

Method Detail

reload

public void reload()

Reload the XSLT file this validator was initialized with.

Specified by:

reload in interface DocumentValidator

Throws:

ValidatorException - If there is an error reloading the file, or if this validator was initialized with an input stream.

validate

public ValidationResult validate(byte[] source)
                          throws ValidatorException

Validate the given XML document, and return a new ValidationResult structure containing the validation results.

Specified by:

validate in interface DocumentValidator

Parameters:

source - Byte-array containing the XML document to validate

Returns:

A newly initialized ValidationResult containing the results of the validation

Throws:

ValidatorException - Thrown when there is an error performing the validation

validate

public ValidationResult validate(byte[] source,
                                 ValidationResult result)
                          throws ValidatorException

Validate the given XML document, and add the validation results to the given ValidationResult structure

Specified by:

validate in interface DocumentValidator

Parameters:

source - Byte-array containing the XML document to validate

result - The structure to add the validation results to

Returns:

The modified ValidationResult instance

Throws:

ValidatorException - Thrown when there is an error performing the validation

setupTransformer

protected Transformer setupTransformer()

Initialize the Saxon Transformer

loadTransformer

protected Transformer loadTransformer(InputStream inputStream)

Load the transformer in the given input stream.

Parameters:

inputStream - The input stream containing the XSLT

Throws:

ValidatorException - if the transformer cannot be initialized from the given stream data
