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

rubyonrails-talk
1

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 :slight_smile: 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.
