Simple example of fetching data from url and then parsing returned XML

[j...@via.net]

I would like to fetch some database info. I have to construct a url with arguments, send it then parse the returned XML.

I quick example would be nice, but if someone could point out how to do the following tasks, I could probable figure it out. 

1) Performng a http 'fetch'

2) Parking XML. There must me a library or gem for this...

Thanks,

Joe

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.
