XOM API for Processing XML with Java

[Manfred Lotz <manfred.lotz AT arcor.de>]

Hi all,
I want to modify an xml document by sorting the children of a specific 
element.

Assuming I have something like this:

<a>
 <b key="xyz"> .... </b>
 <b key="sssssyz"> .... </b>
 <b key="eyz"> .... </b>
 <b key="qyz"> .... </b>
 <b key="abc"> .... </b>
</a>

I want to sort the <b> elements according to the key value and write the 
modified xml document to a file.


I can put the <b> elements in Elements
        Elements bElements = doc.getRootElement().getChildElements();

but this gives me iteration only.


How can I do it?
