Class XsltCompiler

public class XsltCompiler extends Object

An XsltCompiler object allows XSLT 2.0 stylesheets to be compiled. The compiler holds information that represents the static context for the compilation.

To construct an XsltCompiler, use the factory method Processor on the Processor object.

An XsltCompiler may be used repeatedly to compile multiple queries. Any changes made to the XsltCompiler (that is, to the static context) do not affect queries that have already been compiled. An XsltCompiler may be used concurrently in multiple threads, but it should not then be modified once initialized.

Since: 9.0

Constructor Detail

XsltCompiler

protected XsltCompiler(Processor processor)
Protected constructor. The public way to create an XsltCompiler is by using the factory method Processor .

Parameters: processor the Saxon processor

Method Detail

compile

public XsltExecutable compile(Source source)
Compile a stylesheet.

Note: the term "compile" here indicates that the stylesheet is converted into an executable form. There is no implication that this involves code generation.

The source argument identifies the XML document holding the principal stylesheet module. Other modules will be located relative to this module by resolving against the base URI that is defined as the systemId property of the supplied Source.

The following kinds of javax.xml.transform.Source are recognized:

Parameters: source Source object representing the principal stylesheet module to be compiled

Returns: an XsltExecutable, which represents the compiled stylesheet.

Throws: SaxonApiException if the stylesheet contains static errors or if it cannot be read. Note that the exception that is thrown will not contain details of the actual errors found in the stylesheet. These will instead be notified to the registered ErrorListener. The default ErrorListener displays error messages on the standard error output.

getErrorListener

public ErrorListener getErrorListener()
Get the ErrorListener being used during this compilation episode

Returns: listener The error listener in use. This is notified of all errors detected during the compilation. Returns null if no user-supplied ErrorListener has been set.

getURIResolver

public URIResolver getURIResolver()
Get the URIResolver to be used during stylesheet compilation.

Returns: the URIResolver used during stylesheet compilation. Returns null if no user-supplied URIResolver has been set.

isCompileWithTracing

public boolean isCompileWithTracing()
Ask whether trace hooks are included in the compiled code.

Returns: true if trace hooks are included, false if not.

isSchemaAware

public boolean isSchemaAware()
Ask whether schema-awareness has been requested by means of a call on XsltCompiler

Returns: true if schema-awareness has been requested

Since: 9.2

setCompileWithTracing

public void setCompileWithTracing(boolean option)
Set whether trace hooks are to be included in the compiled code. To use tracing, it is necessary both to compile the code with trace hooks included, and to supply a TraceListener at run-time

Parameters: option true if trace code is to be compiled in, false otherwise

setErrorListener

public void setErrorListener(ErrorListener listener)
Set the ErrorListener to be used during this compilation episode

Parameters: listener The error listener to be used. This is notified of all errors detected during the compilation.

setSchemaAware

public void setSchemaAware(boolean schemaAware)
Say that the stylesheet must be compiled to be schema-aware, even if it contains no xsl:import-schema declarations. Normally a stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations. If it is not schema-aware, then all input documents must be untyped, and validation of temporary trees is disallowed (though validation of the final result tree is permitted). Setting the argument to true means that schema-aware code will be compiled regardless.

Parameters: schemaAware If true, the stylesheet will be compiled with schema-awareness enabled even if it contains no xsl:import-schema declarations. If false, the stylesheet is treated as schema-aware only if it contains one or more xsl:import-schema declarations.

Since: 9.2

setURIResolver

public void setURIResolver(URIResolver resolver)
Set the URIResolver to be used during stylesheet compilation. This URIResolver, despite its name, is not used for resolving relative URIs against a base URI; it is used for dereferencing an absolute URI (after resolution) to return a javax.xml.transform.Source representing the location where a stylesheet module can be found.

This URIResolver is used to dereference the URIs appearing in xsl:import, xsl:include, and xsl:import-schema declarations. It is not used at run-time for resolving requests to the document() or similar functions.

Parameters: resolver the URIResolver to be used during stylesheet compilation.
