Hi
I am using XMLBeans version 2.1.0 and have got a question about how the
XMLStreamReader handles namespaces and in particular why the semantics
used by the newXMLStreamReader() method and the xmlText() method are
different when passed the same set of XmlOptions. This is best
illustrated by an example:
Map ns = new HashMap();
ns.put( EBXML_NAMESPACE_URI, EBXML_NAMESPACE_PREFIX );
XmlOptions xmlOptions = new XmlOptions();
xmlOptions.setSaveOuter();
xmlOptions.setSaveSuggestedPrefixes( ns )
xmlOptions.setSaveAggressiveNamespaces().setSaveImplicitNamespaces( ns
);
MessageHeaderDocument messageHeaderDocument =
MessageHeaderDocument.Factory.newInstance();
MessageHeaderDocument.MessageHeader messageHeader =
messageHeaderDocument.addNewMessageHeader();
messageHeader.setVersion( "2.0" );
FromDocument.From from = messageHeader.addNewFrom();
PartyIdDocument.PartyId fromPartyId = from.addNewPartyId();
fromPartyId.setType( "urn:nhs:names:partyType:ocs+serviceInstance"
);
fromPartyId.setStringValue( "from_party_key" );
...
The output from the messageHeaderDocument.xmlText( xmlOptions ) looks
like:
<eb:MessageHeader
xmlns:eb="http://www.oasis-open.org/committees/ebxml-msg/schema/msg-head
er-2_0.xsd" eb:version="2.0">
<eb:From>
<eb:PartyId
eb:type="urn:nhs:names:partyType:ocs+serviceInstance">from_party_key</eb
:PartyId>
</eb:From>
</eb:MessageHeader>
The output from messageHeaderDocument.newXMLStreamReader( xmlOptions )
looks like:
<MessageHeader
xmlns="http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-
2_0.xsd"
xmlns:axis2ns1="http://www.oasis-open.org/committees/ebxml-msg/schema/ms
g-header-2_0.xsd"
axis2ns1:version="2.0">
<From>
<PartyId
xmlns:axis2ns2="http://www.oasis-open.org/committees/ebxml-msg/schema/ms
g-header-2_0.xsd"
axis2ns2:type="urn:nhs:names:partyType:ocs+serviceInstance">from_party_k
ey</PartyId>
</From>
</MessageHeader>
As you can see the namespaces, whilst valid, have not been prefixed
correctly or managed aggressively when using the XMLStreamReader
approach. Does this seem like odd behaviour or is this expected? From
looking at the 2.1.0 source the only options newXMLStreamReader() pays
attention to are saveInner and saveOuter, why is this?
I am writing an object that is a wrapper round an XmlObject and want to
expose an XMLStreamReader as part of that interface, but due to this
namespacing issue I'm considering exposing an InputStream instead, based
on the String returned from the xmlText() method. This seems a bit hacky
and I'm also concerned that it's not going to be the most efficient. I'm
using the result of that method as the input to a StAXOMBuilder so that
I can generate AXIOM classes for use in an axis 2 request. Has anyone
used a similar approach?
Thanks in advance for any help with this.
