It's not real sophisticated, but you might want to check out my
DOCTYPEChanger, which lets you specify a DOCTYPE.  It's a Java
FilterReader (or FilterStream) which strips out the old DOCTYPE (if you
insist) and puts in a new one.


You can put it in front of an XML parser if you want, or just run documents through it.
