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 ?
