java - Pass xml document as parameter to xsl

Question

I have read a lot of post and tried a lot of things but still can't get the xsl to find values in the parameter. I started with java's sun xalan and never got it working so I switched to saxon to no avail. I want to combine two xml docs into one with xls. Never are on a file system, this is for a web app that builds xml strings/ docs. I have tried passing an DTMAxisIterator, DomSource , Doc to Node set in xsl, string. It worked fine in NotePad++ with an xsl document() but I don't want to save the xml on the system.

XSL

<xsl:param name="RsXml" select="/"/>

<xsl:template match="/policy/vehicles">
<vehicle type="DP" type_code="DP"/>

        <xsl:for-each select="$RsXml/InsuranceSvcRs /com.csc_PolicyOrderCurrentCarrierInqRs/PersVeh">

Answer 1

I was able to get it work with Saxon see below code. I think the key was the document.getDocumentElement() as parm

      public String transformResultXML(String xmlSource, Templates xsl,String policyXml )    {
       String result = "";  

    try {

          StringWriter writer = new StringWriter();
          StringReader reader2 = new StringReader(policyXml);

          DocumentBuilderFactory dfactory =
                  DocumentBuilderFactory.newInstance( "com.icl.saxon.om.DocumentBuilderFactoryImpl",null);

          dfactory.setNamespaceAware(true);

          DocumentBuilder docBuilder = dfactory.newDocumentBuilder();

          org.w3c.dom.Document document = docBuilder.parse(new InputSource(new StringReader(xmlSource)));

          Transformer transformer = xsl.newTransformer();

          transformer.setParameter("RsXml", document.getDocumentElement());

          transformer.setOutputProperty(OutputKeys.INDENT, "yes");
          transformer.transform(new javax.xml.transform.stream.StreamSource(reader2),
                  new javax.xml.transform.stream.StreamResult(writer));
          result = writer.toString();
          System.out.println(result);

    } catch( Exception e ) {
        e.printStackTrace();
    }
