Hello *,
I'm just trying to deserialise BPEL files with xmlbeans.
The problem, I stumbled over is, that I do not find an adequately
simple possibility to get an order-preserving access to elements,
which are specified as
<group ref="bpws:activity" maxOccurs="unbounded"/>
in the XML Schema. bpws:activity is specified as the list of
alternatives
<group name="activity">
<choice>
<element name="empty" type="bpws:tEmpty"/>
<element name="invoke" type="bpws:tInvoke"/>
<element name="receive" type="bpws:tReceive"/>
<element name="reply" type="bpws:tReply"/>
<element name="assign" type="bpws:tAssign"/>
<element name="wait" type="bpws:tWait"/>
<element name="throw" type="bpws:tThrow"/>
<element name="terminate" type="bpws:tTerminate"/>
<element name="flow" type="bpws:tFlow"/>
<element name="switch" type="bpws:tSwitch"/>
<element name="while" type="bpws:tWhile"/>
<element name="sequence" type="bpws:tSequence"/>
<element name="pick" type="bpws:tPick"/>
<element name="scope" type="bpws:tScope"/>
</choice>
</group>
. Unfortunately, xmlbeans does not seem to give me a container, where
all elements occur in parse order. Instead, I get a set of arrays like
TInvoke[] getInvokeArray()
TReceive[] getReceiveArray()
and so on. In itself, they seem to be parse-ordered.
Does anybody know of a proper work-around?
One idea could be to apply a semantically equivalent transformation
on the bpel.xsd, which would motivate the xmlbeans parser generator
to generate a collection, spanning all alternatives at once.
Or is there any other information about the parse-ordering of the
elements, which could eventually be evaluated? No global counter or
a timestamp, fine-grained enough to be unique? Or does anybody see
a good method to inject this information, if not there?
Any ideas?
Thanks for listening to my bubbles.
Bye,
Markus
