This vt.py can you use to get the vehicle-positions of the NS-trains in a /tmp/data.xml file. It is recieved from a ZMQ-stream.

1. You must have an account at NDOVloket.nl, so create them.
2. Some lines in this code are commented. Just play with it to adjust your script.
3. Uncomment #call(["vt_process.php"])
4. Create a PHP-script to read your tmp/data.xml
5. Give the vt.py script executable right: chmod +x vt.py
6. Run this script: nohup ./vt.py > /dev/null 2>&1 &
7. Check if tmp/data.xml is updated.

Have fun!
