Parsing through files is a common thing to do. In python I'd just read each line of the file and remember the last line to get the XY coordinates to calculate the new offsets when you encounter a G2 or G3. I've written several G code generators you can see them on the wiki for inspiration. Look at the Arc Generator for my code to calculate arcs.
