Glen Daniels commented on WSCOMMONS-10: --------------------------------------- > FYI : The correct solution for this is to implement the NamespaceContext in > our parser wrapper. Sure. But that means both a) we should implement getNamespaceContext(), and b) we should ensure that getNamespacePrefix()/getNamespaceURI() work correctly. > So shall we agree to fix this for 1.1 and wait for 1.0, please ? Hm - I would really much rather fix this now. The current situation seems to be as follows - I can't hand an XMLStreamReader which I've gotten from a pre-built OM to another piece of code (databinding, XQuery engine, whatever) and expect that the namespace mappings will work. Right? If so, this is awful if I've got any QNames that the application needs to resolve itself (in attribute / element values)! Plus, I would think getNamespaceContext() gets some actual use, and if we don't support it no code that uses it will work with our reader.... +1 to fix this in 1.0. > Request to have a utility method to get a copy of child OMElement whose > namespaces may be declared at parent OMElements > ----------------------------------------------------------------------------------------------------------------------- > > Key: WSCOMMONS-10 > URL: http://issues.apache.org/jira/browse/WSCOMMONS-10 > Project: WS-Commons > Type: Improvement > Components: AXIOM > Reporter: Raymond Feng > > Here's the topic we discussed at Axis2 mailing list. > Raymond Feng wrote: > > Hi, > > > > I have an OM containment hiearchy as "SOAPEnvelope --> SOAPBody --> > > OMElement e1" and the namespace xmlns:ns1="http://ns1"; is declared at > > the SOAPEnvelope level (I observe that It's the behavior when the > > SOAPEnvelope is received from the Axis2 engine). > > > > XMLStream reader = e1.getXMLStreamReader(); > > > > For the reader, I found "reader.getNamespaceCount()" returns 0.
