Subject: Re: Help with HTML parsing

you can also use ruby library Sanitize (http://wonko.com/post/sanitize)

This library can make you parse html template very easily.

let's see the following examples.

Using Sanitize is easy. First, install it:
  sudo gem install sanitize

Then call it like so:

  require 'rubygems'
  require 'sanitize'

  html = '<b><a href="http://foo.com/">foo</a></b><img src="http://foo.com/bar.jpg 
" />'

  Sanitize.clean(html) # => 'foo'

By default, Sanitize removes all HTML. You can use one of the built-in  
configs to tell Sanitize to allow certain attributes and elements:

  Sanitize.clean(html, Sanitize::Config::RESTRICTED)
  # => '<b>foo</b>'

  Sanitize.clean(html, Sanitize::Config::BASIC)
  # => '<b><a href="http://foo.com/" rel="nofollow">foo</a></b>'

  Sanitize.clean(html, Sanitize::Config::RELAXED)
  # => '<b><a href="http://foo.com/">foo</a></b><img src="http://foo.com/bar.jpg 
" />'

Or, if you¡¯d like more control over what¡¯s allowed, you can provide  
your own custom configuration:

  Sanitize.clean(html, :elements => ['a', 'span'],
      :attributes => {'a' => ['href', 'title'], 'span' => ['class']},
      :protocols => {'a' => {'href' => ['http', 'https', 'mailto']}})

good one :)
