XMLBeans DOM Document

[Mohana Ramaratnam <mo...@npg.wustl.edu>]

I am trying to get a DOM document to be then used with Xalan's XPathAPI.
This is the code that I have:

 

        String xmlFile = "dom.xml"; 

            XmlObject xmlObject = new XmlReader().read(xmlFile);

            DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();

            // MUST be TRUE or can't get back to bean land

            factory.setNamespaceAware(true);

            DocumentBuilder builder = factory.newDocumentBuilder();

            // Switch to org.w3c.dom.Document - xmlbeans.getDomNode()
doesn't

            // really seem to give you this

            ByteArrayOutputStream out = new ByteArrayOutputStream();

            xo.save(out,new XmlOptions().setSavePrettyPrint());

            Document doc = builder.parse(new InputSource(new
ByteArrayInputStream(out.toByteArray())));

NodeList nodes = XPathAPI.selectNodeList(doc,"/Pipeline");

           System.out.println("Number of nodes is " +
nodes.getLength());

           DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();

           DocumentBuilder builder = dbf.newDocumentBuilder();

           Document doc1 = builder.parse( new File(xmlFile));

           NodeList nodes1 = XPathAPI.selectNodeList(doc1,"/Pipeline");

           System.out.println("Number of nodes is " +
nodes1.getLength());

 

I get two different answers in the system out. Any ideas as to what
could be wrong in creating a DOM document from a XMLBeans object?

Mohana,
 
I would look in the "out" byte array and see what it looks like. By
doing xo.save(...) (by the way, who is "xo"?) you completely bypass
XmlBeans, so it's a matter of what document are you really loading.
 
It would be more interesting, from an XmlBeans perspective, to know what
results you get from XmlObject.getDomNode() and XmlObject.newDomNode()
