Xmlstarlet, aka sed for xml, makes it easy to find out when the bus is going to arrive at a stop in Edinburgh without having to leave the command line:
curl -s 'http://www.mybustracker.co.uk/display.php?clientType=b&busStopCode=36253282' | xmlstarlet sel -N x=http://www.w3.org/1999/xhtml -t -m //x:pre -c 'text()' -n
The output looks like this (bus number, destination, minutes until arrival):
10 WESTRN HARBOUR 14 10 WESTRN HARBOUR 43 11 ST ANDREW SQ 10 11 OCEAN TERMINAL 22 12 SEAFIELD 4 16 SILVERKNOWES 3
You can get the bus stop codes from the bus tracker website. Of course, you could just get the times from there too, but where’s the fun in that?
