I am far from expert, but I'd start by using wget to get the file locally, then cat the file and parse it. I think wget can output to a pipe, but it makes debugging harder. Depending on cutting method, several tools can be used to snip the data.

In any case, you need a script. Add wget and cat the result, maybe to grep so you can find what you want. Someone better at Linux tools can help you cut the text you want.
