Used for transformations with compiled style sheets.
IXSLProcessor is designed to handle asynchronous transformations. In this case, multiple calls to the transform method must be made, in which each call will transform as much as it can based on what is available from the input. In this scenario, the processor remains in READYSTATE_INTERACTIVE until the transform is complete.

The style sheet — "d:\\inetpub\\wwwroot\\sampleXSLWithObject.xml"
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:myObj="urn:my-object">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<xsl:element name="bar">
<xsl:value-of select="myObj:get-text()"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output (in a message box)
<?xml version="1.0" encoding="UTF-16"?> <bar> foo </bar>
The createProcessor method returns IXSLProcessor. The processor has a transform method that takes the input data, applies the XSL Transformations (XSLT) style sheet defined in the IXSLTemplate, and writes the result to the specified output stream.
This XSL processor is completely independent of the transformNode and transformNodeToObject methods on DOMDocument. In particular, when you transform XML using IXSLProcessor, the ontransformnode event is not fired on DOMDocument.
