title: XML attribute access in AS3
body: <p>I have an xml file (loaded in with URLLoader) that looks like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;root&gt;
      &lt;localizations&gt;
          &lt;words&gt;
              &lt;Brand us="Brand Here"&gt;&lt;/Brand&gt;
          &lt;/words&gt;
      &lt;/localizations&gt;
      &lt;world squareunits="100"&gt;&lt;/world&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p>Once loaded,what is the quickest way to access <strong><em>world.squareunits</em></strong> with E4X or just pure AS3?</p>
