How to use GML-data?


I'm totally newbie with everything, but I'll try to express my problem as well as I can.

I need to read open data from here:

These are written with Geography Markup Language (GML), apparently some open standard implementation based on xml or something like that. I can't find any nodes on Knime which would support that and I need much more training before I can do that from scratch.

Any ideas how that should be done or has somebody already done something like that? I suppose that, as it should be some sort of standard language, I'm not the first one trying this with Knime.

Thanks a lot for help in advance!

I think a "R snippet" node can help:
