What is faster for you if you work with a dom in memory.
1\ To create a reader with the dom and next to pass the reader to create a
dtm.
2\ To work with DOM2DTM
I currently work with xml4j and I have probleme with the DOM2DTM, but if
it's much faster than the first solution, i'm going to try more.

Slight quibble: Xalan-J builds a DTM _proxy_ to the DOM. A fair amount of
information does wind up being replicated for speed-of-execution reasons,
but we do avoid recopying #PCDATA, and some of the other info is also
retrieved from the DOM only when needed. And we build the proxy
incrementally, which may allow us to avoid constructing all of it.
So DOM2DTM isn't really a "second copy" of the DOM document. But yes, the
proxy layer does impose a significant amount of overhead compared to the
"native" DTM.
