Can I use Hpricot to parse data into different array elem?

Ruby

Hi,

I have a question about using Hpricot.

Say I have a file search.html that contains the following:

  •         <a

    href=“http://www.sheetmusicplus.com/title/Holst-G-Wind-Quintet-Set/5015093”>Holst
    G /Wind Quintet (Set)

      <span class="price">$21.95</span>

  •         <a

    href=“http://www.sheetmusicplus.com/title/Holst-G-Wind-Quintet-Score/5014486”>Holst
    G /Wind Quintet(Score)

    •       <span class="price">$15.95</span>

    And I want to use Hpricot to parse it and have each price matched with
    its title.

    If I do something like this

    doc = open(“F:/search.html”) { |f| Hpricot(f) }
    doc.search(".price").each do |price|
    prices = [price.inner_text]
    puts prices[0]

    =>$21.95
    $15.95

    Then it seems that my search results are in an array, but that both
    prices are in a single element in the array because both come up when I
    ask for the element at [0]
    I’m a ruby newbie–what am I missing?
    Thanks very much

    Not understanding loops? Better variable names?

    require ‘rubygems’
    require ‘hpricot’

    doc = open(“html.txt”) { |f| Hpricot(f) }

    doc.search(".price").each do |price_tag|
    price = price_tag.inner_text
    puts price
    end

    –output:–
    $21.95
    $15.95
