Hello everybody.
It is seams to me a little strange that no one mentioned about the XERCES
DOM implementation by Apache.
The best way to guarantee for at least the well formatted XML is to use the
standard API for that.
Build the DOM tree ( as you like - it is your business model ) and serialize
it to XML using XML serializer class in Xerces Java parser API.
You can do everything you want ( including validation against the DTD
constraints ) having the built DOM tree.
Tree structure by itself guarantees you'll get the well formatted XML
document at your final output. ;-)
Good luck.
