xsl:function not working for me?

[Guest chris_almond79]

chris_almond79@lycos.comHi all, thanks to whoever is taking the time to read this...I'm trying to get xsl:function working, but I can't seem to find out how to use it.I have found numerous examples an now know how to use the syntax, but what I can't find is how/where to actually define/use the function.I found the attached function at http://www.stylusstudio.com/docs/v2006/d_xslt87.htmlBut when I save it, either as a .xml or .xsl file, and open it in Internet Explorer, I just get IE's default representation of a standard xml file. That is, I see the code, not the results of running the function.So how is xsl:function actually used?Do I need an XML file and an XSL file? or can everything be included in the one file as below?Do I HAVE to run it from a web server (eg: http://localhost/) or can it be run straight from my C drive?How can I confirm that I have version 2.0 of XSL?Is this example even valid?Thanks in advance for any advice anyone can give me,Chris.

<xsl:transform   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:xs="http://www.w3.org/2001/XMLSchema"  xmlns:str="http://example.com/namespace"  version="2.0"  exclude-result-prefixes="str">               <xsl:function name="str:reverse" as="xs:string">  <xsl:param name="sentence" as="xs:string"/>  <xsl:sequence       select="if (contains($sentence, ' '))             then concat(str:reverse(substring-after($sentence, ' ')),                         ' ',                         substring-before($sentence, ' '))             else $sentence"/></xsl:function> <xsl:template match="/"><output>  <xsl:value-of select="str:reverse('DOG BITES MAN')"/></output></xsl:template>               </xsl:transform>

xsl:function is an XSLT 2.0 feature. NONE of today's browsers nor their next versions would support it, because XSLT 2.0 is still a candidate reccomendation. Therefore, I suggest you forget about it for now. If you need it, then try to find XSLT 1.0 solution or find a server side scripting parser (such as Saxon) which supports XSLT 2.0.
