XML node reading problem

1

I’ve an XML File like this

   <?xml version="1.0" standalone="yes" ?> 
- <mypictures>
- <family>
  <Abhilash title="WebDesigner" /> 
  <Shon title="Programmer" /> 
  <Rajan title="WebSupport" /> 
  </family>
- <vacation>
  <Siva title="WebAssistant" /> 
  <Reji title="Designer" /> 
  <Sam title="Support" /> 
  </vacation>
  </mypictures>

I can access the first node like this

  
news = new XML();
news.ignoreWhite = true;
news.load("family.xml");
news.onLoad = function(success){
if(success){
rootNode = news.firstChild.firstChild;
}

The result contains [Abhilash to Rajan]
The file will be populated with more nodes on later . But i want to know how to access the second child of the root node
It is possible like

 
rootNode = news.firstChild.firstChild.nextSibling;

Result contains [Sive to Sam ]
But the file populated with more node i don’t think it is a good practice. Any other way to get the rest of the nodes in the future. :red:
