Although it is not standard, it is possible to execute JavaScript functions from within your XSLT.

With MSXML you can use the msxsl:script extension element.

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

<msxsl:script language="JScript" implements-prefix="user">
  function getUser()
  {
   return user;
  }

</msxsl:script>

<xsl:template match="/">
   <xsl:value-of select="user:getUser(.)"/>
</xsl:template>

</xsl:stylesheet>

Also remember to add DEFER attrinute.

 <SCRIPT LANGUAGE="javascript" DEFER="true">
  <xsl:comment>

function hiLite()
 {
   alert("hello");
 }

</xsl:comment>
</SCRIPT>
