Detailed Description

Serves as an interface to a XSLT processor. The following example shows how to apply an XSL Transformation to a XOM document and get the transformation result in the form of a XOM Nodes:

  public static Nodes transform(Document in)
     throws XSLException, ParsingException, IOException {
#include <elm/xom/Builder.h>
#include <elm/xom/XSLTransform.h>
 
Builder builder = new Builder();
Document *stylesheet = builder.build("mystylesheet.xsl");
XSLTransform transform(stylesheet);
Nodes nodes = transform.transform(doc);

Constructor & Destructor Documentation

XSLTransform() [1/2]

XSLTransform

(

Document *

stylesheet

)

Creates a new XSLTransform by reading the stylesheet from the supplied document.

Parameters

stylesheet

document containing the stylesheet

Exceptions

XSLException

when the supplied document is not syntactically correct XSLT

XSLTransform() [2/2]

XSLTransform	(	Document *	stylesheet,
		NodeFactory *	factory
	)

Creates a new XSLTransform by reading the stylesheet from the supplied document. The supplied factory will be used to create all nodes in the result tree, so that a transform can create instances of subclasses of the standard XOM classes. Because an XSL transformation generates a list of nodes rather than a document, the factory's startMakingDocument and finishMakingDocument methods are not called.

Parameters

stylesheet	document containing the stylesheet
factory	the factory used to build nodes in the result tree

Exceptions

XSLException

when the supplied document is not syntactically correct XSLT

Member Function Documentation

setParameter() [1/2]

void setParameter	(	const string &	name,
		const string &	ns,
		const string &	value
	)

Supply a parameter to transformations performed by this object.

Parameters

name	the name of the parameter
namespace	the namespace URI of the parameter
value	the value of the parameter

setParameter() [2/2]

void setParameter	(	const string &	name,
		const string &	value
	)

Supply a parameter to transformations performed by this object.

Parameters

name	the name of the parameter
value	the value of the parameter

Note

The parameter value must be a valid XPath expression, meaning that,

• strings must be quoted with "'",
• boolean value must converted to integer (zero for false, non-zero for true) or using functions true() or false().

toDocument()

Document * toDocument

(

const Nodes &

nodes

)

Creates a new Nodes object from the input Nodes object by applying this object's stylesheet. The original Nodes object is not changed.

Parameters

in	document to transform

Returns

a Nodes containing the result of the transformation

Exceptions

XSLException

if the transformation fails, normally due to an XSLT error all nodes passed in in parameter are cleaned up

References ParentNode::appendChild(), Node::ELEMENT, NodeFactory::finishMakingDocument(), Nodes::get(), Node::kind(), Document::setRootElement(), Nodes::size(), and NodeFactory::startMakingDocument().

toString()

String toString

(

void

)

Returns a string form of this XSLTransform, suitable for debugging.

Returns

debugging string

References Document::toString().

transform() [1/2]

Nodes transform

(

Document *

in

)

Creates a new Nodes from the input Document by applying this object's stylesheet. The original Document is not changed.

Parameters

in	document to transform

Returns

a Nodes containing the result of the transformation

Exceptions

XSLException

if the transformation fails, normally due to an XSLT error

transform() [2/2]

Nodes transform

(

Nodes

in

)

Not currently supported.

transformDocument()

Document * transformDocument

(

Document *

in

)

Transform a document and return it.

Parameters

in	document to transform.

Returns

transformed document.
