Calling PHP functions from XSLT (evil...)

• You can call now any PHP functions as an XSLT-Function

  function foo($id ) {
    return $id;
  } 
  function bar($id) {
    return $id[0]->value;
  }  
  function nodeSet($id = null) {
    $dom = new domdocument;
    $dom->loadXML("<root>this is from an external DomDocument</root>");
    return $dom->documentElement;
  }
  $xslt = new xsltprocesser();
  $xslt->registerPhpFunctions();
  
  ---
  <xsl:value-of select="php:functionString('foo', /doc/@id)"/>
  <xsl:value-of select="php:function('bar', /doc/@id)"/>
  <xsl:value-of select="php:function('nodeSet')/root"/>
