in jdom you would just parse then take the root, then the employee,
the extract last-name and ssn.
It is ignoring from the point of view of your programme but not from
the point of view of parsing.
Where you can save is by changing the xml technology... if your
document is as simple as below then using sax has greater performance
guarantees (you really cannot go faster) but is harder to programme
Another part where jdom can take too much of your CPU is if this
document has loads of other stuffs.
Where JDOM would make a positive difference is at walking more
elaborate xml documents, which is the norm, and at manipulating them.
The expressivity of the library there is unbeatable to my taste.
However, your requirements sound easy: 8500 such documents per minutes?
JDOM does this probably ten times, multithreadedness not being really
