You can also take a look at XmlObject.selectChildren() as in:
HeaderT hdrT = (HeaderT) soapHdr.selectChildren(new QName("hmf854.v1",
"header");

Subject: RE: Re: XML Beans usage question
Hi Jerome
The SOAP envelope schema simply says that the SOAP Header element can
contain "anything". Generated XmlObjects do not provide getters and
setters for "anything" (this is under discussion - there are some
technical details which make it tricky - for instance you can have more
than one "anything") so the current recommended approach is to rely on
the XmlCursor.
Detail on how to navigate around any XML document using the XmlCursor
are given at
http://xmlbeans.apache.org/docs/2.0.0/guide/conNavigatingXMLwithCursors.
html (in general http://xmlbeans.apache.org/documentation/index.html is
a good place to start).
In your case you can parse the SOAP information and get the SOAP header
as you are doing:
File msgFile = new File(reqMsgDocFilename); EnvelopeDocument soapEnvDoc
= EnvelopeDocument.Factory.parse(msgFile);
Envelope soapEnv = soapEnvDoc.getEnvelope(); Header soapHdr =
soapEnv.getHeader();
Then you can get an XmlCursor positioned just before the start token of
the SOAP header by doing:
XmlCursor cursor1 = soapHdr.newCursor();
Then navigate to the SOAP Header's first child (which is your <header>
element):
cursor1.toFirstChild();
(If you had a different setup there are many other APIs available on
XmlCursor - e.g. you can navigate specifically to a child with a given
QName using toChild(QName)).
Then get an XMLStreamReader
XmlStreamReader rdr = cursor1.newXMLStreamReader();
or you could get the text itself as a String
String internalHdrAsString = cursor1.xmlText());
whichever you like. Then you can parse (I've used the reader below - you
could just as well pass in the String):
tmf854.v1.HeaderDocument internalHdrElement = tmf854.v1.
HeaderDocument.Factory.parse(rdr);
After this you should be able to do
internalHdrElement.getActivityName(). (You already have
elementFormDefault="qualified" for that schema - so it's correct that
your instance doc refers to the internal elements using their
namespaces).
And don't forget to call cursor1.dispose() at the end.
Not sure why the approach using DOM doesn't work - I don't know a lot
about that part of the code - but one of the reasons for XmlCursor is to
be there is specifically to help solve this kind of issue - so the
approach above should work. The only tricky thing with XmlCursor is to
be sure exactly which token the cursor is pointing to at any point in
time - the link I gave above and this one
(http://xmlbeans.apache.org/docs/2.0.0/guide/conUnderstandingXMLTokens.h
tml) should help with this.
Cheers,
Lawrence
