Subject: Shoes GUI - downloading site, using reg exs on body

So I want my app to download the text of a site's body (easy) and then I
want to use regular expressions to pick out chunks of text.

In my very limited skills/knowledge, I've had a hard time getting this
working.  I've tried two approaches...


Code:

Shoes.app do

  stack :left => 65, :top => 75 do
    @results = para "results"
  end

  stack (:left => 165, :top => 180) do
    para "URL:"
      flow do
        button "Clear" do
          @status.replace "results cleared..." and
          @searching.replace " " and
          @results.replace "results"
        end
        @url = edit_line "http://www.google.com/"
        button "OK" do

    stack do
         @searching = title "Searching site", :size => 16
          @status = para "One moment..."
            download @url.text do |site|
              @status.text = "Body: " + site.response.body.inspect
              regex = Regexp.new(/http/)
              matchdata = @status.text
                if matchdata
                    @results.text = matchdata[1]
                else
                    @results.text = "NO MATCH"
                end
              end
          end
        end
      end
    end
end


That doesn't work.

This is the other approach:
              @status.text = "Body: " + site.response.body.inspect
        if @status.text =~ /html/ then
         @results.text = $1

Any advice/guidance?  Am I even on the right track?
