Or perhaps even that the XML structure is incorrectly
defined, and shouldn't have such huge text nodes.
It's also good to note that independent of the size of
individual text nodes, JDom by default always builds
the full document, so even though the underlying
parser may report bigger text as smaller chunks, this
doesn't necessarily help a lot, unless builder

Exactly. JDom implements the document tree model, and
defers parsing (and optionally, deserialization) to a
low-level streaming parser.
Besides SAX parsers, you can also have look at StAX
parser, since for these kinds of tasks, it may be an
even better fit. There is a Stax-based JDom builder
(which is a sub-project of Woodstox Stax XML
Or, you may choose to leave JDom out altogether, for
this special case. Handling of huge XML files is one
area where many standard processing components
(DOM/JDom/Dom4j, XSL) may not be usable, and you need
to use more lower level methods (or perhaps streaming
