msxsl:script Element

Appears at the top level of the style sheet and contains script blocks that define global variables and functions for script extensions.

<msxsl:script
  language = "language-name"
  implements-prefix = "prefix of user's namespace">
</msxsl:script>

Attributes

language

Active Scripting language used for the functions defined within this element. If left unspecified, the current scripting language is used, as specified by a language attribute on an ancestor. If no such attribute exists, JScript® (compatible with ECMA 262 language specification) is used. This attribute accepts the same values as the language attribute on the HTML <SCRIPT> element.

implements-prefix

Required. Declares a namespace and associates it with the script block. The value of this attribute is the prefix which represents the namespace.

Element Information

Remarks

Belongs to the namespace urn:schemas-microsoft-com:xslt. You can declare variables and define functions within the <msxsl:script> element. This can appear within the <xsl:stylesheet> element. A script block thus nested is treated as a global script block.

You can also instantiate COM objects in the <msxsl:script> element. However, a user's security settings may prevent your script from instantiating a client-side object.

Example

This example creates a script block with a namepace prefix of "user" that contains a function called "xml" that takes a node-list as an argument. Later, this function is called from the select attribute of <xsl:value-of>.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                xmlns:user="http://mycompany.com/mynamespace"
                version="1.0">
  <msxsl:script language="JScript" implements-prefix="user">
    function xml(nodelist) {
      return nodelist.nextNode().xml;
    }
  </msxsl:script>
  
  <xsl:template match="/">
    <xsl:value-of select="user:xml(.)"/>
  </xsl:template>
</xsl:stylesheet>
