Ah, interesting. If it was me, I think I'd grab the complete number and round to the nearest integer, by adding 0.5 and then truncating the fractional part. I'd also note that another part of the XML file suggests checking the file at 15 minutes after the hour, as it apparently takes a while to process the measurement. If you ask at the top of the hour, the measurement you get is over an hour old. The two relevant elements are: <suggested_pickup>15 minutes after the hour</suggested_pickup> <suggested_pickup_period>60</suggested_pickup_period> -- Russell Senior russ...@personaltelco.net
