Hi,
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetData xmlns="http://.intel.com/WSS/GetData">
      <loginName>testuser</loginName>
      <password>123@wss)</password>
      <CurrentVersion>10</CurrentVersion>
      <ModTypeCode>string</ModTypeCode>
      <ParamList>string</ParamList>
      <PrufFileType>string</PrufFileType>
    </GetData>
  </soap:Body>
</soap:Envelope>

I'm trying to access the "GetData" element using the XPath "/soap:Envelope/soap:Body/GetData", but that doesn't return me anything. But if I remove the "xmlns" from "GetData", I'm able to access it. Now the client gives me the XML String in the above fashion only, I wonder how I can get access to the inner elements of GetData.

Please help.

Thanks,
Praveen

The GetData element is in the namespace "http://.intel.com/WSS/GetData" so you need to use the XPath expression "/soap:Envelope/soap:Body/data:GetData" in which the "soap" prefix is bound to "http://schemas.xmlsoap.org/soap/envelope/" and the "data" prefix to "http://.intel.com/WSS/GetData". Of course you can use different prefixes provided you bind them to the correct namespace URI. The way you bind namespace prefixes when evaluating an XPath expression depends on the environment in which you are using XPath.

Incidentally, your question has nothing to do with namespace nodes.
