Parse byte stream from HTTP Poll of XML adapter

I have created an HTTP Poll operation using ES XML adapter.
Now that I receive the byte stream which is byte, which contains XML document, how do I Parse that Byte stream using ParseXML config op or do I have to use one of the standard parsers like xerces in a custom step method?

use the parsexml operation and choose byte as input type and the rest are pretty easy to follow. but i was you, i would use IS for all xml operations. good luck
