Using XSLT to Transform an XML Tree

You can create an XML tree, create an XmlReader from the XML tree, create a new document, and create an XmlWriter that will write into the new document. Then, you can invoke the XSLT transformation, passing the XmlReader and XmlWriter to the transformation. After the transformation successfully completes, the new XML tree is populated with the results of the transform.

Dim xslMarkup As XDocument = _ 
    <?xml version='1.0'?>
    <xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0'>
        <xsl:template match='/Parent'>
                    <xsl:value-of select='Child1'/>
                    <xsl:value-of select='Child2'/>

Dim xmlTree As XElement = _ 
        <Child1>Child1 data</Child1>
        <Child2>Child2 data</Child2>

Dim newTree As XDocument = New XDocument()

Using writer As XmlWriter = newTree.CreateWriter()
    ' Load the style sheet.
    Dim xslt As XslCompiledTransform = _
        New XslCompiledTransform()

    ' Execute the transform and output the results to a writer.
    xslt.Transform(xmlTree.CreateReader(), writer)
End Using


This example produces the following output:

  <C1>Child1 data</C1>
  <C2>Child2 data</C2>
