Hello

Does somebody have a sample code in Python to download the schedule ? Hopefully without installing a bunch of plugins.

thanks

Simple Retrieval of XML data with Python.

Usage with gzipped=True may or may not work. Retrieval with the defaults works just peachy and results in a latin-1 encoded XML document stored in the file specified.

Simply provide a username and password and the data will be retrieved and stored to disk.

If you break it, you own both halves.

Any chance you (or someone else) could post an updated version that works on Yosemite (Mac OS X 10.10) and with the necessary changes for the new URLs?

Thanks,
Dave

Here is updated code with the passwords removed -- it is currently working for me against the new servers.

There are two changes:
1) the URL is changed to point to the new server
2) the HTTP Authorization Handler is changed from HTTPDigestAuthHandler() to HTTPBasicAuthHandler()

The new server does not presently support Digest authentication -- though it may again in the future.
