The problem appears now, because I have to parse a document containing a lot of information. DOM is not enough to accomplish the object because the document is extremly large, and I don't know how SAX deals with this kind of files.

  Well if you're ready to go C or Python, libxml2 recent versions can handle
(and validate) very large XML instances using an API based on C# xmlReader,
there are documentation at
   http://xmlsoft.org/xmlreader.html
 Note that you can ask to expand a subtree and use XPath on it for convenience.
I Relax-NG validated a 4.5GByte instance with it a couple of months ago 
(on a 32bits architecture).
