[jdom-interest] new to jdom .. and many questions

[Azrael]

Of course, you're very much correct regarding my first question.. it's
late and I wasn't thinking straight :)
I badly explained with extra detail what would have been simpler with a
shorter question.. of how to find if it was the very last element or not.
I don't really want to be learning to use XPATH in java right now.. and 
so will go for the iterating method you suggest..
finding next sibling as you say is easy enough.. but I am a little 
unsure about how to navigate the jdom tree breadth first using the 
Lists.. does anyone have example code that I could use as a guide?

would improve man, but it would deteriorate the cat.
