title: Get tag by specified text
body: <p>I need a simple solution for getting the DOM tag which contains a given text.</p>
  
  <p>eg.</p>
  
  <pre><code>&lt;body&gt;
     &lt;div id='example'&gt;Hello world!&lt;/div&gt;
  &lt;/body&gt;
  
  &lt;script&gt;
    function GetTagInfo('Hello');
   //I wan't it to return the div as the object so I'll next update the    //content with another text. 
  &lt;/script&gt;
  </code></pre>
  
  <p>I don't want to use any regex, I need clean and simple code.</p>
