XPathDocument Input to XslTransform
The XPathDocument is a read-only cache, for processing documents with XslTransform. It is structurally similar to the XML Document Object Model (DOM), but it is highly optimized for Extensible Stylesheet Language for Transformations (XSLT) processing and the XML Path Language (XPath) data model using the XPath optimization functions on the XPathNavigator.
Note
The XslTransform class is obsolete in the .NET Framework version 2.0. You can perform Extensible Stylesheet Language for Transformations (XSLT) transformations using the XslCompiledTransform class. See Using the XslCompiledTransform Class and Migrating From the XslTransform Class for more information.
The following code sample creates an XPathDocument as input to a transform.
Dim xslt as XslTransform = new XslTransform()
Xslt.Load(someStylesheet)
Dim doc as XPathDocument = New XPathDocument("books.xml")
Dim fs as StringWriter = new StringWriter()
Xslt.Transform(doc, Nothing, fs, Nothing);
XslTransform xslt = new XslTransform();
Xslt.Load(someStylesheet);
XPathDocument doc = XPathDocument("books.xml");
StringWriter fs = new StringWriter();
Xslt.Transform(doc, null, fs, null);
