Question

I have some difficulties to parse an XML using Stax in order to create org.w3c.dom.Document objects for parts of the XML tree.

Ex.:
<root>
<children>
<child>child 1</child>
<child>child 2</child>
<child>child 3</child>
</children>
</root>
=> I would like to create 3 DOM objects for each <child> node.

I tried to do this using Staxmate and DomConverter but I have a problem ...

My test project only depends on :

  • stax2-api-3.0.3.jar
  • staxmate-2.0.0.jar
  • jdk 1.6.0_21

2 tests :

  • Test 1 that works perfectly


    FileInputStream in = new FileInputStream("demo.xml");
    XMLStreamReader sr = XMLInputFactory.newInstance().createXMLStreamReader(in);
    Document doc = new DOMConverter().buildDocument(sr);
    in.close();

  • Test 2 that throws a HIERARCHY_REQUEST_ERR exception :


    FileInputStream in = new FileInputStream("demo.xml");
    XMLStreamReader sr = XMLInputFactory.newInstance().createXMLStreamReader(in);
    while (sr.hasNext()) {

      sr.next();
      switch (sr.getEventType()) {
        case XMLStreamReader.START_ELEMENT:
          Document doc = new DOMConverter().buildDocument(sr);
      }
    }
    in.close();



    org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted.

Could you help me please ?
