Trouble requesting string from XML via Comm.makeWebRequest

Hi,

I am having trouble extracting text from an internet XML.
I am currently trying to replicate this using the webRequest call but am not sure if
A) it is possible
B) what content type call i should be using.

Comm.makeWebRequest(

            "synd.cricbuzz.com/.../livematches.xml",

            {

                "Cricket" => "Awesome",

                "ConnectIQ" => "1337"

            },

            {

                "Content-Type" => Comm.REQUEST_CONTENT_TYPE_URL_ENCODED

            },

            method(:onReceive)

        );

    }

Thanks in advance
