XContainer.CreateWriter Method

Creates an XmlWriter that can be used to add nodes to the XContainer.

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

'Declaration
Public Function CreateWriter As XmlWriter

Return Value

Type: System.Xml.XmlWriter
An XmlWriter that is ready to have content written to it.

While serializing, namespace prefixes are inferred from the namespace attributes in the XML tree.

For more information, see Working with XML Namespaces.

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

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'>
            <Root>
                <C1><xsl:value-of select='Child1'/></C1>
                <C2><xsl:value-of select='Child2'/></C2>
            </Root>
        </xsl:template>
    </xsl:stylesheet>

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

Dim newTree As XDocument = New XDocument()

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

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

Console.WriteLine(newTree)

This example produces the following output:

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