title: Retrieving variables (document metadata) from a MultiMarkdown document with PHP
body: <p>How can I retrieve <strong>MultiMarkdown <em>document metadata</em></strong> (as defined <a href="http://github.com/fletcher/MultiMarkdown/wiki/MultiMarkdown-Syntax-Guide" rel="nofollow">here</a>) using php?
  I was rather surprised that I couldn't find a MultiMarkdown php parser, <a href="http://michelf.com/projects/php-markdown/extra/" rel="nofollow">PHP Markdown Extra</a> doesn't do MultiMarkdown.</p>
  
  <p>I'm afraid that <a href="https://github.com/fletcher/MultiMarkdown" rel="nofollow">the scripts</a> that MultiMarkdown's comes packaged with have all the answers for somebody that would know how to define/use a custom XSLT, but sadly that's not my case. </p>
  
  <p>MultiMarkdown <em>Document Metadata</em> goes like this:</p>
  
  <blockquote>
    <p>Title:  A New MultiMarkdown Document<br>
    Author: Fletcher T. Penney<br>
            John Doe<br>
    Date:   July 25, 2005  </p>

  <p>I would like to use my own properties and control where they will be displayed in the output. By default, mmd2XHTML outputs the above (pre-defined) variables in   tags, but I need to display them somewhere in the HTML body.</p>
  
  <p>thanks</p>
