Make .find non case sensitive
<p>I can currently using:</p>

<pre><code>$results.find('a[href$=".doc"]')
</code></pre>

<p>to find anything ending with .doc for editing reasons.  However, this seems to be case sensitive, i.e. if a document ends with .DOC or .Doc, it will not find those.  Is it possible to make this non case sensitive?</p>
