Suggestions for parsing ASP string

I’m trying to build an image gallery with a backend connection. My ASP is returning the following string format;

[COLOR=DarkRed]uniqueid=1,mm_name=bluehills.jpg,mm_path=img/req1,mm_keywords=keyword1[/COLOR]&[COLOR=Blue]uniqueid=2,mm_name=satellite_map.jpg,mm_path=img/req2,mm_keywords=map satellite[/COLOR]&[COLOR=DarkOliveGreen]uniqueid=3,mm_name=robot.jpg,mm_path=img/req2,mm_keywords=robot black and white[/COLOR]

i’m not sure of the best way to parse the string in AS3? I’m looking for suggestions. I imagine a custom XML parsing class? I’d like to bind certain variable to repeater and I need to concatenate things like image path from the string (i.e. “mm_path + mm_name = img/req1/bluehills.jpg”).

I’m looking for any suggestions on what road to take and perhaps any links for previous examples? Preemptive double-thank you!
