Re: Parsing Returned XML String

Mon, 15 Jan 2007 05:35:05 -0800

Thilina,

Thanx for the reply. Attached is the modified and cleaned-up original code as well as the result of the Ant build/run. It still appears that all of the returned XML is being treated as a single string and does not break out correctly when parsed. I probably misread your instructions so feel free to correct. Ignore the Java warning since it is on an unrelated source file.

Thanx,
Garth

Hi Garth,
You should be able to do this with Axiom itself...
         opts.setAction("urn:wsgetVendor");
         client.setOptions(opts);
         OMElement res = client.sendReceive(createPayLoad());
You can use the "res" OMElement to access it's children...
Try adding the following to here..
         Iterator children = res.getChildren();
        while (children.hasNext())
         {
             OMNode node = (OMNode) children.next();
            System.out.println(node.toString());
         }

         XMLStreamReader reader = XMLInputFactory.newInstance()
                 .createXMLStreamReader(
                         new
ByteArrayInputStream(res.toString().getBytes()));
         StAXOMBuilder builder = new StAXOMBuilder(reader); // get the root
No need to do the above, since you already have a Axiom in place with
the web service response....

You can find some articles & tutorials about Axiom from here [1].

Thanks,
Thilina
