Is this to run as a background task or from the command line or from a
user request to a rails app?

I assume you mean parsing :) Have a look at nokigiri. In fact I
believe that will fetch it from a url for you. The answer to question
1 is still important as it is not advisable to run code fetching from
a url in a request from a user. No doubt when you googled for ruby
xml parsers you found others, they may well be perfectly acceptable
but I have not tried any of them.
