Support for the msxsl:node-set() Function

  • Artigo

The msxsl:node-set function enables you to convert a result tree fragment into a node set. The resulting node set always contains a single node and is the root node of the tree.

Note

The XslTransform class is obsolete in the .NET Framework 2.0.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 msxsl:node-set function enables you to convert a result tree fragment into a node set. The resulting node set always contains a single node and is the root node of the tree.

Example

In the following example, $books is a variable that is a node tree in the style sheet. The for-each statement combined with the node-set function allows the user to iterate over this node tree as a node set.

nodeset.xsl

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"  
                xmlns:user="https://www.contoso.com"  
                version="1.0">  
    <xsl:variable name="books">  
        <book author="Michael Howard">Writing Secure Code</book>  
        <book author="Michael Kay">XSLT Reference</book>  
    </xsl:variable>  
  
    <xsl:template match="/">  
        <authors>  
            <xsl:for-each select="msxsl:node-set($books)/book">
                <author><xsl:value-of select="@author"/></author>  
            </xsl:for-each>  
        </authors>  
    </xsl:template>  
</xsl:stylesheet>

Output

The output of the transformation is

<?xml version="1.0" encoding="utf-8"?>  
<authors><author>Michael Howard</author><author>Michael Kay</author></authors>
