No, JDOM does not require it. But the existing builders (such as SAXBuilder) 
load the whole XML document in memory and do not give you the possibility to 
only process portions of it.

But JDOM allows you to create your own builders. As our project needs to 
process megabyte-large XML files, I wrote a builder that takes XPath 
expressions and only creates the elements matching those expressions.
I'm working with Jason to make it available in the jdom-contrib module.

In the mean time, if you are interested in getting it, just drop me a mail.
