title: Alternative to getElementsByTagName
body: <p>Since the getElementsByTagName() function is new (DOM-1?) I wanted another more reliable method to get a reference to an element based on its tag name/id.</p>
  
  <p><strong>Edit-</strong>  Without using a framework, since I need to cut down on size; so 10-20K for a framework is unacceptable. I just need the JS code that can fetch an element</p>
