The Tcl implementation of TclDOM (and TclXML, the package that
actually does the parsing) is naturally quite slow.
MSXML is implemented in C++.

There is now a version of TclDOM that uses libxml2.
libxml2 is written in C and is *very* fast.  By comparison,
I ran some simple tests over the weekend and TclDOM/libxml2
is more than 20 times faster than TclDOM/tcl (and by inference
is faster than MSXML).

It would appear that you are using MS Windows.  I'm cc'ing this
message to the tclxml-users mailing list in case anyone has
built TclDOM/libxml2 for Windows and might be willing to
share it.

Other alternatives are TclDOMPro (part of the TclDOM distribution)
or tDOM (different API).

Cheers,
Steve Ball
