JQuery manipulation of a SELECT element
<p>I am doing some manipulation of the options contained in a Select element. Is there a way to</p>

<ul>
<li>remove all elements</li>
<li>Search an element in the list of already present options</li>
<li>update an option attribute (e.g. set as selected)</li>
</ul>

<p>I am using jQuery 1.4.3</p>
