I have following xslt , I need to use xslt version 2.0 functions like 'format-date'. How do I declare the Xsl sheet to use version 2.0 using XsltCompiledTransform class (c#, .net 4.5).

 <xsl:stylesheet version="2.0"

回答1:

Microsoft's XslCompiledTransform is an XSLT 1.0 processor. To use XSLT 2.0 with .NET, you have two third party options, the .NET version of Saxon 9 from http://saxon.sourceforge.net/ or XmlPrime. Saxon has an open source version HE and two commercial versions PE and EE, XmlPrime for commercial use requires a license.

As Martin wrote, Microsoft's processor only supports 1.0 - even now, in 2016. I had a similar problem (I needed to do work with regular expressions within my XSLT) and I resolved it by using inline C# to do the work.

I based my solution on this example: XSLT Stylesheet Scripting Using <msxsl:script> (MSDN)

You'll have to add a few things to your xsl:stylesheet node. Mine looks like:

<xsl:stylesheet version="1.0"
            xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
            xmlns:msxsl="urn:schemas-microsoft-com:xslt"
            xmlns:user="urn:my-scripts"
            exclude-result-prefixes="msxsl">

Then, you'll define your script. Mine was something like:

<!-- Script to check for URLs in values -->
<msxsl:script language="C#" implements-prefix="user">
    <![CDATA[
      public string ExtractUrl(string str)
      {
          return Regex.Match(str, @"(https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*))").Value;
      }
    ]]>
</msxsl:script>

I was then able to invoke the function within my XSLT:

<xsl:variable name="extractedUrl" select="user:ExtractUrl(.)"></xsl:variable>

It's not mentioned on the tutorial page, but where I processed the XSLT on the server, I also had to create an XsltSettings object to enable script execution:

XsltSettings settings = new XsltSettings(false, true); // enable script execution
XsltCompiledTransform transform = new XslCompiledTransform();
transform.Load("template.xsl", settings, new XmlUrlResolver());

Of course, consider security - make sure your XSLT file contains only trusted and/or sanitized input if you're allowing the execution of arbitrary C# scripts.

As an addendum to the approved answer, here's an expansion on @TonyP's comment on using Microsoft's format-date.

MSDN Documentation on format-date: https://msdn.microsoft.com/en-us/library/ms256099%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

Example

<xsl:stylesheet 
    version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
    exclude-result-prefixes="xsl msxsl"
>

<!-- ... --->
<td class="redb"><xsl:value-of select="msxsl:format-date(RequiredBy,'d MMMM yyyy')"/></td>
<!-- ... --->

NB: MS's options for formatting dates are far less rich that those available in XSLT 2.0 (see documentation); so I believe the d MMMM yyyy format is the closest you can get to the format you're after.
