Example for Traversal Methods: Rewriting an Attribute

My test line

The approximative code:

 <h2 id="myh2">My test line</h2>
 document.childNodes[0].childNodes[1].childNodes[2].childNodes[1].style.color="red";
 document.getElementsByTagName("h2")[0].style.color = "yellow";
 document.getElementById("myh2").style.color = "white"; 

Effects:

• Search through the tree for the node to be changed
• Search through the list of h2 nodes
• Change attribute on node with the specified Id

Note that the first method is very sensitive to changes in the document!
