title: Get Child Nodes By Tag Name in DOM
body: <p>I know that in DOM, the Document object has the method <strong>getElementsByTagName()</strong>.</p>
  
  <p>Why is this operation not defined on any particular Node? Suppose I have a Node object, and I want to find a particular child of that Node by name. Do I really have to implement my own method to traverse all its children until I find the one with that name? (I am not using XPath.) Sounds like a lot of work for a simple task. Thanks</p>
