While I agree about the mess, XMLSpy generates the attached from the supplied XML.  Compiling these with XMLBeans appears to let you address elements below the "command" level:

    {

        IqDocument  doc     = IqDocument.Factory.parse(new File("getProfile.xml"));

        Iq          iq      = doc.getIq();

        Command     command = iq.getCommand();

        Iodata      iodata  = command.getIodata();

        System.out.println("Iodata: "+iodata);

    }

This is quite a mess. I'm assuming you have to accept the input as is.



Basically you've got 4 different XML vocabularies active in each xml

instance doc:

      * The 1st one, which isn't in any namespace at all, containing

        only the {iq} element as well as ALL the attributes in ALL the

        elements (yes, ALL)

      * a 2nd containing only the {command} element

      * a 3rd containing the {iodata, out} elements

      * a 4th containing the {profiles, profile, actions, action}

        elements.



Note that, according to the XML namespace spec, unqualified attributes

are in NO namespace (not even the default) whereas unqualified elements

are in the default namespace (assuming a default ns has been declared).



[ sidenote: I doubt this effect was intended by design here. If it won't

get you into trouble, do smack the author ever so gently at the back of

the head. :-) ]



Given that an .xsd can define a schema for only a single namespace I

think you're going to have to create a separate .xsd for each of the

above namespaces and set the targetNamespace to the appropriate xmlns.

I'm not absolutely sure but I think for the "no namespace" stuff (i.e.

<iq> and all the attributes) you should create an .xsd without a

targetNamespace attr -- don't make it empty, leave it out entirely.



Alternatively, you might be able to get away with creating a single "no

namespace" .xsd and turning off namespace processing when parsing the

xml docs. However, I'm not sure XmlBeans or Jaxb can function this way.
