Did you know you can use VBScript in XSLT files?
Sample script which goes after the xslt namespace:
<msxml:script language="VBScript" implements-prefix="VBCustomScript"> <![CDATA[ function VBCustomScript(str) VBCustomScript= "test" & str end function ]]> </msxml:script>
add to xslt namespace:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxml="urn:schemas-microsoft-com:xslt" xmlns:VBCustomScript="#VBCustomScript" >
in xslt:
<xsl:value-of select=""VBCustomScript:VBCustomScript(string(@Field))""/>
