Yeah, I`m trying to develop a simple application using ruby (when this works i will pass to rails). I need get the source code from a URL, and find for this string: <h3 class="zmp">$299.99</h3> wow, but i need search for not only 149.00, but for all possible numbers, my friend suggest this: <h3 class="zmp">*$\d+\.\d{2}.*</h3> i think this works! but i need other thing... look my code: #!/usr/bin/ruby require 'hpricot' require 'open-uri' @content = Hpricot(open(" http://www.newegg.com/Product/Product.aspx?Item=N82E16855101066")) now how i can find for <h3 class="zmp">*$\d+\.\d{2}.*</h3> ? @content.search("<h3 class="zmp">*$\d+\.\d{2}.*</h3>") is broken ;( how i can solved this? thanks for you attention, Luiz Vitor Martinez Cardoso. -- Regards, Luiz Vitor Martinez Cardoso [Grabber].

Don't use the regex. Let hpricot do what it's good at:
$ irb >> require 'rubygems' >> require 'hpricot' >> html = '<h3 class="zmp">149.00</h3>' >> doc = Hpricot.parse(html) >> ele = doc.search('h3.zmp') >> puts ele.text => 149.00 In your code, your @content will be searchable the same way. Hpricot will give you a collection of all h3's with class 'zmp'. http://code.whytheluckystiff.net/doc/hpricot/ Hope this s.
