title: Automatic highlight code in a wordpress blog
body: <p>I've a self installed wordpres blog full of Python snippets and I'd like to have them highlighted (source code colored). I tried to install a couple of plugins like <a href="http://wordpress.org/tags/wp-syntax" rel="nofollow noreferrer">wp-syntax</a> and <a href="http://wordpress.org/tags/wp-syntax" rel="nofollow noreferrer">Jquery.Syntax</a> but they require me to edit all my posts adding some attrs to the pre tags.</p>
  
  <p>How can I hack into the plugins or wordpress in other to apply the plugins to all the pre tags?</p>
