<msxsl:script> Element

noteNote:
This element is supported only in the .NET Framework.

One, and only one, of the attributes must be specified in this element.

The name form of the attribute can specify the assembly file name in either a simplified or full form as shown in the following examples.

<ms:assembly name="System.Xml"/>
<ms:assembly name="System.Xml, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

The href form of the attribute can specify the assembly name as either a file path or a URI as shown in the following examples.

<ms:assembly href="Helper.dll"/>
<ms:assembly href="C:\MyApplication\Helper.dll"/>
<ms:assembly href="http://tempuri.org/Helper.dll"/>

The assembly path name is resolved twice - once during compilation and once during execution. The rules during compilation are same as the compiler rules. If a fully qualified path to the assembly is not provided, the current directory is searched for the specified assembly. If not found, the common language runtime (CLR) system directory is searched. If not found, the directories specified in the LIB environment variable are searched.

During execution, the .NET Framework loader rules are used. The current directory is searched first, followed by the global assembly cache (GAC), followed by any rules specified in the application configuration file.

The following assemblies are referenced by default:

  • System.dll

  • System.Xml.dll

  • Microsoft.VisualBasic.dll (if Visual Basic is used)

The following example demonstrates accessing a class in a user-defined assembly named MyCompany.HelperAssembly.

This is the C# code contained in the MyCompany.HelperAssembly assembly.

namespace MyCompany.XmlHelper
{
   public class NodeContents
   {
      XPathNavigator _nav;

      public NodeContents(XPathNavigator nav)
      {
         _nav = nav;
      }

      public string GetNodeContents()
      {
         return _nav.InnerXml;
      }
   }
}

The following stylesheet adds a reference to the assembly and imports the appropriate namespace. The classes in the assembly namespace are referenced in the script block.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                xmlns:user="http://MyCompany/"
                version="1.0">

  <msxsl:script language="C#" implements-prefix="user">
    <msxsl:assembly name="MyCompany.HelperAssembly" />
    <msxsl:using namespace="MyCompany.XmlHelper" />
    public string FragmentValue(XPathNavigator nav)
    {
       NodeContents myContents = new NodeContents(nav);
       return myContents.GetNodeContents();
    }
  </msxsl:script>
  

    <xsl:template match="/">
            <xsl:value-of select="user:FragmentValue(customer[1])"/>
    </xsl:template>
</xsl:stylesheet>
