title: Regex help (extracting data between hr tags)
body: <p>I'm trying to extract teaser text within TinyMCE in a PHP CMS. The <code>&lt;hr /&gt;</code> tag is not used within my design, so I'd like to extract the text in the following scenarios, based on the assumption that the content administrator will ONLY use them to define Teaser text:</p>
  
  <ol>
  <li><p>Extract content before an <code>&lt;hr /&gt;</code> tag (in the situation the content administrator enters the teaser text at the beginning of the RTE, and then uses <code>&lt;hr /&gt;</code> as the cuttof point)</p></li>
  <li><p>Extract the content between 2 <code>&lt;hr /&gt;</code> tags (in the situation where the content administrator enters the teaser text anywhere within the content, and indicates it with <code>&lt;hr /&gt;</code> tags on either side.</p></li>
  </ol>
  
  <p>What regex should I use to cover the above?</p>
