Hi all, I am interested in writing a method that takes input as a hash and creates/appends to an xml file. The idea is everytime a hash reference is passed to the method when the method is called, it must add a child node to the xml node. ie. for the first time, it must create a xml file with the the following nodes 
<a>
 <b>
   <c>
   <d>
   <e>
 </b>
</a>

The next time the method's called. If the file's existent, it must append the new hash to the existing xml file. It must have the following structure: 
<a>
 <b>
   <c>
   <d>
   <e>
 </b>
 <b>
   <c>
   <d>
   <e>
 </b>
   .
   .
</a>

I understand XML::WRITER can help you create such a tree, but I think I would also have to parse the file if existent and then append to it. Could someone tell me how so do i use it to create the file and then just parse it and append child nodes to existing XML file whenever the method's called.
Thanks
