The "[BING_MAP_KEY]" is apparently already expanded in the initial sQuery string, so that line is not needed.

It also looks like to parse the return you're looking for "coordinates" and then the text between "[" and "]" after that. It looks like this in general form:

{"type":"Point","coordinates":[0.000000,0.000000]}
