Target the last word within an <h1> element
<p>Does anybody know whether this can be achieved in jQuery. Target/addClass to the last word of an element, in this case the word 'Text' within a h1 tag. Bear in mind I know I can target the last word with a span tag but I'm working with a CMS that has something like %My_heading% markup. (not exactly but I'm hoping this is understood) </p>

<pre><code>&lt;h1&gt;Some Heading Text&lt;/h1&gt;
</code></pre>
