Web/API/XSLTProcessor

Non-standard This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

An XSLTProcessor applies an XSLT stylesheet transformation to an XML document to produce a new XML document as output. It has methods to load the XSLT stylesheet, to manipulate <xsl:param> parameter values, and to apply the transformation to documents.

Syntax

The constructor has no parameters.

new XSLTProcessor()

Methods

[Throws] void XSLTProcessor.importStylesheet(Node styleSheet)

Imports the XSLT stylesheet. If the given node is a document node, you can pass in a full XSL Transform or a literal result element transform; otherwise, it must be an <xsl:stylesheet> or <xsl:transform> element.

[Throws] DocumentFragment XSLTProcessor.transformToFragment(Node source, Document owner)

Transforms the node source by applying the stylesheet imported using the XSLTProcessor.importStylesheet() function. The owner document of the resulting document fragment is the owner node.

[Throws] Document XSLTProcessor.transformToDocument(Node source)

Transforms the node source applying the stylesheet given importing using the XSLTProcessor.importStylesheet() function.

The resultant object depends on the output method of the stylesheet:

Output method	Result type
html	HTMLDocument
xml	XMLDocument
text	XMLDocument with a single root element <transformiix:result> with the text as a child

[Throws] void XSLTProcessor.setParameter(String namespaceURI, String localName, any value)

Sets a parameter in the XSLT stylesheet that was imported. (Sets the value of an <xsl:param>.) A null value for namespaceURI is treated the same as an empty string.

[Throws] any XSLTProcessor.getParameter(String namespaceURI, String localName)

Gets the value of a parameter from the XSLT stylesheet. A null value for namespaceURI is treated the same as an empty string.

[Throws] void XSLTProcessor.removeParameter(String namespaceURI, String localName)

Removes the parameter if it was previously set. This will make the XSLTProcessor use the default value for the parameter as specified in the stylesheet. A null value for namespaceURI is treated the same as an empty string.

void XSLTProcessor.clearParameters()

Removes all set parameters from the XSLTProcessor. The XSLTProcessor will then use the defaults specified in the XSLT stylesheet.

void XSLTProcessor.reset()

Removes all parameters and stylesheets from the XSLTProcessor.

Properties

Non-Web-exposed properties

The following properties are [ChromeOnly] and not exposed to Web content:

[ChromeOnly] attribute unsigned long XSLTProcessor.flags

Flags that tweak the behavior of the processor. Not reset by calling XSLTProcessor.reset(). Default value: 0

Possible values are:

Name	Value	Effect
(None)	0	None
DISABLE_ALL_LOADS	1	Disable loading external documents (via e.g. <xsl:import> and document())
