title: Regex for parsing directory and filename
body: <p>I'm trying to write a regex that will parse out the <strong>directory and filename</strong> of a fully qualified path using matching groups.</p>
  
  <p>so...</p>
  
  <pre><code>/var/log/xyz/10032008.log
  </code></pre>
  
  <p>would recognize <code>group 1 to be "/var/log/xyz"</code> and <code>group 2 to be "10032008.log"</code></p>
  
  <p>Seems simple but I can't get the matching groups to work for the life of me.</p>
  
  <p>NOTE:  As pointed out by some of the respondents this is probably not a good use of regular expressions.  Generally I'd prefer to use the file API of the language I was using.  What I'm actually trying to do is a little more complicated than this but would have been much more difficult to explain, so I chose a domain that everyone would be familiar with in order to most succinctly describe the root problem.</p>
