[jira] Resolved: (XMLBEANS-222) new XmlStreamReader from XmlObject doesn't capture xsi namespace in outer element

Cezar Andrei resolved XMLBEANS-222:
-----------------------------------

    Resolution: Fixed

There are two things happening here:
1. the semantics of XmlObject.newXMLStreamReader() is not exactly the same as XMLInputFactory.newInstance().createXMLStreamReader(). The difference is that it doesn't emit the start/end doc events, this is because in general an XmlObject represents the content and there isn't a special case for a Document XmlObject.
2. Once you get an XMLStreamReader the code calls imediately next() which advances the reader to the next event after Soaf:Envelope, so efectively missing the namespaces.
 		while (reader.hasNext()) {
			int event = reader.next();


To catch the namespaces in question the test code has to be modified in one of the two following ways:

1) add an option to start with START_DOC event
        XmlOptions opts = new XmlOptions().setSaveOuter();
        XMLStreamReader reader = object.newXMLStreamReader(opts);

2) or modify the logic to check the first event
        XMLStreamReader reader = object.newXMLStreamReader();

        boolean foundXsiNamespace = false;
        int event = reader.getEventType();
        do
        {
            if (event == XMLStreamReader.START_ELEMENT)
            {
                for (int i = 0; i < reader.getNamespaceCount(); i++)
                {
                    if (reader.getNamespacePrefix(i).equals("xsi"))
                    {
                        foundXsiNamespace = true;
                    }
                    System.out.println("  testXMLStreamReader Namespace " + reader.getNamespacePrefix(i) + " : " +
                        reader.getNamespaceURI(i));
                }
            }
            event = reader.next();
        }
        while (reader.hasNext());
        System.out.println("    xsi Namespace: " + foundXsiNamespace);

>   Components: XmlObject

>     Reporter: Brian Bonner
>  Attachments: XmlStreamReaderTest.java

> I'll attach a test case.
> I'm parsing a SOAP envelope which has the xsi namespace declared in the outer envelope.  An element of the body uses the prefix for one of it's attributes (i.e. xsi:nil="true").
> reader.getNamespaceCount() doesn't seem to find it.  If we create the XMLStream from a reader using an InputFactory (vs. using the creator from JSR173.class, it works, but will probably be slower.)
