Html parser with regex, how to solve?

Ruby
1

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:

$299.99

wow, but i need search for not only 149.00, but for all possible
numbers, my
friend suggest this:

*$\d+\.\d{2}.*

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

$\d+.\d{2}.

?

@content.search(“

$\d+.\d{2}.

”) is broken ;(

how i can solved this?

thanks for you attention,

try this:

ele.text.sub(’$’, ‘’)

Don’t use the regex. Let hpricot do what it’s good at:

$ irb

require ‘rubygems’
require ‘hpricot’
html = ‘

149.00

’
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’.

Hope this helps.
