Using Regular Expression in Javascript to grab text between RSS/XML tag

Question

I'm creating a jQuery Mobile app that parses an RSS feed and dynamically inputs the entries into the DOM. I'm using the .contentSnippet feature to grab the first sentence or two from the <description>...</description> and I'd like to just have the content between .... How do I select this content using Javascript and RegEx? Here is what the RSS looks like that I'm working with.

<description><![CDATA[American Banker Magazine (03/13) Fest, Glen...</description>

I'm bringing the feed in as a JSON object.

If you are sure you want to use a regular expression, you could use

var str = '<description><![CDATA[<font size="2"><em>American Banker Magazine (03/13) Fest, Glen</em>...</description>',
    m = str.match( /<em>(.+?)<\/em>/ );

console.log( m && m[1] || 'Nothing doing' );
// American Banker Magazine (03/13) Fest, Glen
