Hi Rob, I only have to read values from nodes but I am amazing by what you say. But the XML file can take 10 Mb. I thought that expat was the faster parser because I have found this link http://www.xml.com/lpt/a/37. Maybe it was true in 1999 but it isn't not at all.
You have to notice that the parser has to be a modular one that I can call in C++ method. Could RegExp be more efficient and faster than a classical Parser XPat or MSXML ? More than that, I have heard that there is another generation which combine DOM and SAX parser, it is a microsoft I think but I have lost the name.
