Member Function Documentation

clearParameters()

void Xslt30Processor::clearParameters

(

bool

deleteValues = false

)

Clear parameter values set.

Default behaviour (false) is to leave XdmValues in memory. Individual pointers to XdmValue objects have to be deleted in the calling program.

Parameters

deleteValues

- if true then XdmValues are deleted

compileFromAssociatedFile()

XsltExecutable * Xslt30Processor::compileFromAssociatedFile

(

const char *

sourceFile

)

Get the stylesheet associated.

Note: the term "compile" here indicates that the stylesheet is converted into an executable form. The compilation uses a snapshot of the properties of the Xslt30Processor at the time this method is invoked.

Parameters

sourceFile

- The file name of the XML document.

Returns

an XsltExecutable, which represents the compiled stylesheet. The XsltExecutable is immutable and thread-safe; it may be used to run multiple transformations, in series or concurrently.

compileFromFile()

XsltExecutable * Xslt30Processor::compileFromFile

(

const char *

stylesheet

)

compile a stylesheet file.

Note: the term "compile" here indicates that the stylesheet is converted into an executable form. The compilation uses a snapshot of the properties of the Xslt30Processor at the time this method is invoked.

Parameters

stylesheet

- The file name of the stylesheet document.

Returns

an XsltExecutable, which represents the compiled stylesheet. The XsltExecutable is immutable and thread-safe; it may be used to run multiple transformations, in series or concurrently.

compileFromFileAndSave()

filename	- the file to which the compiled package should be saved

compileFromString()

XsltExecutable * Xslt30Processor::compileFromString

(

const char *

stylesheet

)

compile a stylesheet received as a string.

bool Xslt30Processor::removeParameter

(

const char *

name

)

Remove a parameter (name, value) pair from a stylesheet

Parameters

name	the name of the stylesheet parameter

Returns

bool - outcome of the removal

setBaseOutputURI()

void Xslt30Processor::setBaseOutputURI

(

const char *

baseURI

)

Set the base output URI.

The base output URI is used for resolving relative URIs in the href attribute of the xsl:result-document instruction; it is accessible to XSLT stylesheet code using the XPath current-output-uri() function

Parameters

baseURI

- the base output URI

setcwd()

void Xslt30Processor::setcwd

(

const char *

cwd

)

set the current working directory (cwd).

This method also applies to the static base URI for XSLT stylesheets when supplied as lexical string. The cwd is used to set the base URI is part of the static context, and is used to resolve any relative URIs appearing within XSLT.

Parameters

cwd	- Current working directory

setFastCompilation()

void Xslt30Processor::setFastCompilation

(

bool

fast

)

Request fast compilation.

Fast compilation will generally be achieved at the expense of run-time performance and quality of diagnostics. Fast compilation is a good trade-off if (a) the stylesheet is known to be correct, and (b) once compiled, it is only executed once against a document of modest size.

Fast compilation may result in static errors going unreported, especially if they occur in code that is never executed.

The current implementation is equivalent to switching off all optimizations other than just-in-time compilation of template rules. Setting this option, however, indicates an intent rather than a mechanism, and the implementation details may change in future to reflect the intent.

Parameters

fast	set to true to request fast compilation; set to false to revert to the optimization options defined in the Configuration.

setJustInTimeCompilation()

void Xslt30Processor::setJustInTimeCompilation

(

bool

jit

)

Say whether just-in-time compilation of template rules should be used.

Parameters

jit

true if just-in-time compilation is to be enabled. With this option enabled, static analysis of a template rule is deferred until the first time that the template is matched. This can improve performance when many template rules are rarely used during the course of a particular transformation; however, it means that static errors in the stylesheet will not necessarily cause the compile(Source) method to throw an exception (errors in code that is actually executed will still be notified to the registered ErrorListener or ErrorList, but this may happen after the compile(Source) method returns). This option is enabled by default in Saxon-EE, and is not available in Saxon-HE or Saxon-PE.

Recommendation: disable this option unless you are confident that the stylesheet you are compiling is error-free.

setParameter()

void Xslt30Processor::setParameter	(	const char *	name,
		XdmValue *	value
	)

Set the value of a stylesheet parameter.

Static (compile-time) parameters must be provided using this method on the XsltCompiler object, prior to stylesheet compilation. Non-static parameters may also be provided using this method if their values will not vary from one transformation to another.

Parameters

name	the name of the stylesheet parameter, as a string. For namespaced parameter use the JAXP solution i.e. "{uri}name"
value	the value of the stylesheet parameter, or nullptr to clear a previously set value

setRelocatable()

void Xslt30Processor::setRelocatable

(

bool

relocatable

)

Indicate package deployable to a different location.

Say whether any package produced by this compiler can be deployed to a different location, with a different base URI

Parameters

relocatable

if true then static-base-uri() represents the deployed location of the package, rather than its compile time location

setTargetEdition()

void Xslt30Processor::setTargetEdition

(

const char *

edition

)

Set the target edition.

Set the target edition under which the stylesheet will be executed.

Parameters

edition

- the Saxon edition for the run-time environment. One of "EE", "PE", "HE", or "JS", "JS2", or "JS3".

setXsltLanguageVersion()

void Xslt30Processor::setXsltLanguageVersion

(

const char *

version

)

Set the XSLT (and XPath) language level to be supported by the processor.

Set the value to "4.0" to enable support for experimental features defined in the XSLT 4.0 proposal (which is likely to change before it stabilizes).

Parameters

version

the language level to be supported. The values "3.0" and "4.0" are recognized

transformFileToFile()

void Xslt30Processor::transformFileToFile	(	const char *	sourcefile,
		const char *	stylesheetfile,
		const char *	outputfile
	)

Perform a one shot transformation.

The result is stored in the supplied outputfile.

Parameters

sourcefile	- The file name of the source document
stylesheetfile	- The file name of the stylesheet document.
outputfile	- The file name where results will be stored

transformFileToString()

const char * Xslt30Processor::transformFileToString	(	const char *	sourcefile,
		const char *	stylesheetfile
	)

Perform a one shot transformation.

The result is returned as a string

Parameters

sourcefile	- The file name of the source document
stylesheetfile	- The file name of the stylesheet document.

Returns

char array - result of the transformation

transformFileToValue()

XdmValue * Xslt30Processor::transformFileToValue	(	const char *	sourcefile,
		const char *	stylesheetfile
	)

Perform a one shot transformation. The result is returned as an XdmValue

Parameters

sourcefile	- The file name of the source document
stylesheetfile	- The file name of the stylesheet document.

Returns

XdmValue - result of the transformation
