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

Hi,

I have a question about using Hpricot.

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

<ul class="search-results-item">
        <li class="search-item-title">

            <a
href="http://www.sheetmusicplus.com/title/Holst-G-Wind-Quintet-Set/5015093">Holst
G /Wind Quintet (Set)</a>
        </li>

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

<li class="search-item-title">

            <a
href="http://www.sheetmusicplus.com/title/Holst-G-Wind-Quintet-Score/5014486">Holst
G /Wind Quintet(Score)</a>
        </li>

          <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
