Axis2 OMElement getAttribute

[Gul Onural]

I have an OMElement response coming from my web services written in
Axis2.

<?xml version="1.0" encoding="UTF-8"?>
<tns:XResponse xmlns:tns="mynamespace"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
   <tns:myObject xsi:type="tns:Type1_T">
      <tns:name>aName</tns:name>
   </tns:myObject>
</tns:XResponse>

On the web services client side, I am trying to determine the xsi:type
attribute value, using following code snippet,
but type (in below code snippet) seems to be null :
        // response is the OMElement shown above.

        Iterator it = response.getChildElements();
        while (it.hasNext()) {
            OMElement element = (OMElement) it.next();
            if ((element.getLocalName()).compareTo("myObject") == 0) {
                OMAttribute type = element.getAttribute(new QName("xsi",
"type"));
                // type is NULL...Why ?????
        }

Could you please let me know what I am doing wrong ?

Thanks
