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.
