How to run a C# function in XSLT?
Answer:
You can add C# functions to your XSLT in 3 easy steps (please check sample code below or download source here):
- Add the namespace declarations:
xmlns:msxsl=urn:schemas-microsoft-com:xsltandxmlns:user=urn:my-scriptsto the style sheet. - To avoid parsing errors declare your function inside a
CDATAsection within themsxsl:scriptelement. - Call your function with parameters like
<xsl:value-of select="user:GetDate('dddd, dd MMMM yyyy')"/>
Tips and Tricks:
- You can add required assemblies (DLL references), namespaces we are using with C# function inside
<msxsl:script />block (checkSystem.Webin our example) - Use
exclude-result-prefixes"user" and "msxsl" to keep your output XHTML clean. - To obtain value from query string, use
System.Web.HttpContext.Current.Request.QueryString["Page"], instead ofRequest.QueryString["Page"].
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="xsl in lang user" xmlns:in="http://www.composite.net/ns/transformation/input/1.0" xmlns:lang="http://www.composite.net/ns/localization/1.0" xmlns:f="http://www.composite.net/ns/function/1.0" xmlns="http://www.w3.org/1999/xhtml" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:user="urn:my-scripts">
<msxsl:script language="C#" implements-prefix="user">
<msxsl:assembly name="System.Web" />
<msxsl:using namespace="System.Web" />
<![CDATA[
public string GetDate(string DateFormat)
{
return DateTime.Now.ToString(DateFormat);
}
]]>
</msxsl:script>
<xsl:template match="/">
<html>
<head />
<body>
<div>
<xsl:value-of select="user:GetDate('dddd, dd MMMM yyyy')" />
</div>
</body>
</html>
</xsl:template>
</xsl:stylesheet>Please read related article "Fetching data in XSLTs using inline C#".
