Talk:Snapshot API

Regex for matching the snapshot API

Eyo! Not sure if anyone would find this useful, but I needed to parse the snapshot api easily, so I wrote a regex, and sharing it here for anyone who may find it useful. Not important enough to go on the wiki page for it, so I put it here as "extra info". It is written in python but should be easy to grab and port over to stuff like perl, ruby, and php.

rePostcardDetails = re.compile(r"<!-- BEGIN POSTCARD DETAILS\n"
 "agent_id=(?P<agent_id>[a-f0-9]{4}(?:[a-f0-9]{4}-){4}[a-f0-9]{12})\n"
 "username=\"(?P<username>[^\"]+)\"\n"
 "region_id=(?P<region_id>[a-f0-9]{4}(?:[a-f0-9]{4}-){4}[a-f0-9]{12})\n"

 "local_z=(?P<local_z>[0-9.]+)\n"
 "END POSTCARD DETAILS -->", re.IGNORECASE)

    test = rePostcardDetails.match("""<!-- BEGIN POSTCARD DETAILS
