How to decode encoded xml in wso2 developer studio proxy service?



I am using oracle provided web service to invoke oracle bi publisher XML report, then I have to read the XML output of report returned by web service.

The issue is, the web service returns the encoded XML, which i have to decode using external decoder. Is there any way i can decode this encoded XML in wso2 developer studio using UTF-8 decoding? so that i can read that XML to proceed further.
