How to retrieve child attribute names in XML?

Question

How do I retieve only the child attribute names from the XML.
XML:
<catalog>
     <book>
           <author></author>
           <title></title>
           <genre></genre>     
           <price></price>    
     </book>
</catalog>Expecting result:
author
title
genre
price
I tried with the SAX Parser and class extending DefaultHandler it returns catalog and book aswell which I do not want to retrieve.
public void startElement(String namespaceURI, String localName,
                                 String qName, Attributes atts)  {
               System.out.println(qName)
//this returns catalog and book along with the other attribute names
}

Your problem is not clear. Are you saying you want only the leaf nodes? Or are you saying you want all the /catalog/book child nodes, even if they're not leaf nodes? Or something else?I do not know what leafy nodes mean but i want to retrieve all the child nodes (tag names).
<catalog>
     <book1>
           <author1></author1>
           <title1></title1>
     </book1>
     <book2>
           <author2></author2>
           <title2></title2>
     </book2>
</catalog>In this example i want to retrieve author1, title1, author2, title2
Also, you're still not specific enough. For instance, what if there's another layer before author and title. Do you want that? What about if there's another level under author and title, do you want that? Can those situations even happen?
Do you want nodes at a certain level?
At a certain level and below?
Always author and title nodes, regardless of where they appear?
Always author and title, but only if they're immediately enclosed by book? Or by book<some number>?
Author and title only when they're under /catalog/book?
If you can't specify your requirements precisely, it's going to be awfully hard for someone to help you.
