With csegRollUp v3 you can use both namespaces in the xml stylesheet.
This example use msxsl namespace with a c# script function to transform a date in a month name:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:utils="urn:script-items">
<msxsl:script language="C#" implements-prefix="utils">
<![CDATA[
public string GetMonth(string sDate)
{
if (sDate.Length > 0)
string[] monthNames = {null , "January" , "February" , "March" , "April", "May",
"June", "July", "August", "September", "October",
"November", "December"};
DateTime d = DateTime.Parse(sDate);
return monthNames[d.Month];
}
else
return "(Empty)";
]]>
</msxsl:script>
<xsl:output method="html" encoding="utf-8" />
<xsl:template match="/Rows/Row">
<li/><b><xsl:value-of select="Title" /></b> - <xsl:value-of select="utils:GetMonth(Fecha)" /><br/>
</xsl:template>
</xsl:stylesheet>
Link with more info XSLT Stylesheet Scripting using <msxsl:script>
This example use exslt distinct function to show only rows with distinct values
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:set="http://exslt.org/sets" exclude-result-prefixes="set">
<xsl:template match="/">
<xsl:for-each select="set:distinct(Row/Estado)">
<xsl:value-of select="." /><br/>
</xsl:for-each>
You can find more information about exslt in exslt.org and Mvp-xml
