title: Getting the content of XHTML tags: p, ul and/or ol from string
body: <p>I have a CMS with a WYSIWYG editor which produces pretty good xhtml. Based on this fact, I think a HTML parser might be slightly overkill for this small job.</p>
  
  <p>I am intending to use regular expressions but so far have been unable to get mine to match what I'm after.</p>
  
  <p>I'm using PHP5.</p>
  
  <p>I need to match the content of the 3 block level elements the WYSIWYG editor is able to produce: p, ul &amp; ol. I am using preg_match_all() currently.</p>
  
  <p>Is anyone able to help me?</p>
  
  <p>Thank you</p>
