One last question: Is it possible, to do the selection directly with XPath... 
What i am doing now, is something like this:
        -create a copy of the document
        -create a List with selectNodes() -method which contains for example 
the 
nodes Year
        -iterate through this list and check with if and getText() if the 
<Year>-tag 
contains 1982. if not, remove the parent tag <Book>

But this seems not very elegant. So is it possible to get a list, which only 
contains the <year> tags which contain 1982 directly per xpath or do i have 
to do the if-checks?
