How do I find all elements with a specific attribute?
<p>I have a number of elements on my page that have a <code>lang</code> attribute.  How do I select only the elements with a <code>lang</code> attribute? </p>

<p>i.e.</p>

<pre><code>&lt;div lang="english"&gt;Test&lt;/div&gt;
&lt;span lang="english"&gt;is cool&lt;/span&gt;
&lt;span lang="anotherlanguage"&gt;is also good&lt;/span&gt;
</code></pre>
