  • 0

I work on an xslt stylesheet, and I should receive as parameter two additional XML. I get an error when I use the node-set() method (from namespace ms, microsoft). The contents of the XML is correct. The parameters are send with classic ASP.

Here’s the header and the call in xslt:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
     xmlns:ms="urn:schemas-microsoft-com:xslt"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
...
<xsl:param name="xmlPlanning"></xsl:param>
<xsl:variable name="myXml" select="ms:node-set($xmlPlanning)"></xsl:variable>
    <xsl:value-of select="ms:node-set($xmlPlanning)/*"/>

Here’s the stack trace of the error:

[XsltException: Impossible de convertir l'opérande en 'fragment de l'arborescence résultat'.]
   System.Xml.Xsl.XsltOld.XsltFunctionImpl.ToNavigator(Object argument) +380943
   System.Xml.Xsl.XsltOld.FuncNodeSet.Invoke(XsltContext xsltContext, Object[] args, XPathNavigator docContext) +33
   MS.Internal.Xml.XPath.FunctionQuery.Evaluate(XPathNodeIterator nodeIterator) +292

[XPathException: Échec de la fonction 'ms:node-set()'.]

   System.Xml.Xsl.XslTransform.Transform(IXPathNavigable input, XsltArgumentList args, TextWriter output, XmlResolver resolver) +43
   System.Web.UI.WebControls.Xml.Render(HtmlTextWriter output) +132

And here’s the beginning of the xml I receive in parameter :

<?xml version="1.0" encoding="UTF-8"?>
<ArrayOfGenerationPlanningDesign xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://webservices.secureholiday.net/">
  <GenerationPlanningDesign>

What could be my problem ?

    node-set() operates on Result Document Fragments (RDFs) only, but you give it a string, which is something entirely different (even if the string contents looks like XML).

    What you must do is parse the string into XML. You can use an extension script for that. The following worked for me (tested with msxsl.exe on the command line), but if you don’t want to use JScript you can use C# or any other supported language to do the same.

    <xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:ms="urn:schemas-microsoft-com:xslt"
  xmlns:script="urn:my-scripts"
  exclude-result-prefixes="ms script"  
>
  <ms:script language="JScript" implements-prefix="script">
    <![CDATA[
    function stringToXml(str) {
      var xml = new ActiveXObject("MSXML2.DOMDocument.4.0");
      xml.async = false;
      xml.loadXML(str);
      return xml;
    }
    ]]>
  </ms:script>

  <xsl:param name="xmlPlanning"></xsl:param>

  <xsl:variable name="myXml" select="script:stringToXml(string($xmlPlanning))" />

  <xsl:template match="/">
    <xsl:value-of select="$myXml/*" /><!-- whatever -->
  </xsl:template>

</xsl:stylesheet>
