title: YUI get element by id method not working for numeric starting ids
body: <p>I've just switched from YUI2 to YUI3. So, instead of using <code>YAHOO.util.Dom.get(ID_OF_ELEMENT)</code>, I tried to use <code>Y.one('#ID_OF_ELEMENT)'</code>. It works fine for a <em>div</em> with <em>id</em> <strong>img123</strong>, but not with <strong>123img</strong> or <strong>123</strong>.</p>
  
  <p>I tried also using <code>Y.all</code> but it didn't work. The only way I found to make it work, while still using YUI, was using <code>Y.DOM.byId</code> (shown as an <a href="http://yuilibrary.com/forum/viewtopic.php?p=7346" rel="nofollow">alternative in YUI forum</a>).</p>
  
  <p>So what I did was to grab the element with the last and get the <em>Node</em> with first, like this:</p>
  
  <pre><code>Y.one(Y.DOM.byId(ID_OF_ELEMENT)).append(SOME_HTML_CONTENT);
  </code></pre>
  
  <p>I could not alone using only <code>Y.DOM.byId</code> because I needed to manipulate it's content as a <em>Node</em>.</p>
  
  <p>So, is there a way to do that using only <code>Y.one</code>? <strong>Is that a YUI bug?</strong></p>
  
  <p>I have made a comment on that <a href="http://yuilibrary.com/forum/viewtopic.php?f=92&amp;t=2169" rel="nofollow">YUI forum entry</a>, since I don't know if that's really a bug I could fill in <a href="http://yuilibrary.com/projects/yui3/report" rel="nofollow">YUI bug reporting tool</a>.</p>
