Xampp, PHP 5.3.0, XSLT Problem

[ab_ay]

I cannot use some xPath functions with xslt in php. For examle I want to use

Code: Select all

   <xsl:template name="create">
      <xsl:for-each select="distinct-values($classpath_elements)">
         <xsl:value-of select="."/>
      </xsl:for-each>
   </xsl:template>


and it gives error for distinct-values function. such as following:
Warning: XSLTProcessor::transformToXml() [xsltprocessor.transformtoxml]: xmlXPathCompOpEval: function distinctvalues not found in C:\xampp\htdocs\iris\index.php on line 24

Warning: XSLTProcessor::transformToXml() [xsltprocessor.transformtoxml]: Unregistered function in C:\xampp\htdocs\iris\index.php on line 24

Warning: XSLTProcessor::transformToXml() [xsltprocessor.transformtoxml]: xmlXPathCompOpEval: parameter error in C:\xampp\htdocs\iris\index.php on line 24

Warning: XSLTProcessor::transformToXml() [xsltprocessor.transformtoxml]: XPath evaluation returned no result. in C:\xampp\htdocs\iris\index.php on line 24

HOW TO SUPPORT THOSE FUNCTIONS WHILE USING PHP XSLT PROCESSOR???? ANY HELP
