WGETting from within rails

i'm writing an app that wants to fetch a URL from a remote server and
return the html text file to the app. i've been told there are some
xml parsers for perl that have request functionality built right in.
is there such a thing for Ruby or if nothing else the possibility of
using WGET from within a Ruby program.

thanks in advance for any help.

you probably want #read in open-uri (or Net::HTTP)
http://www.ruby-doc.org/stdlib/libdoc/open-uri/rdoc/index.html

or you could just backtick:
`curl http::/yourURLhere`

If you just want to fetch the page text :

  require 'open-uri';
  html = open("http://yahoo.com").readlines

  puts html

If you need to extract part(s) of the page, use Hpricot

    require 'rubygems';
    require 'open-uri'
    require 'hpricot'

    doc = Hpricot(open("http://yahoo.com"))

    title = doc.search('title').text
    body = doc.search('body' ).text
    links = doc .search("a").collect{|a| a['href'] }

    puts title
    puts body
    puts links.to_yaml

Hpricot also lets you modify the page contents :
f.ex,
    doc.search('a').each{|link| link.swap(link.inner_html)}

turns all the
     <a href="....">something</a>
into
     something
