Could you provide the file ("file2.html") that you
are using for this
test which fails?  If I use a file like
libxml2/test/HTML/doc2.htm:

billbbopt ~/gnomesvn/work $ ln -s HTML/doc2.htm
file2.html
billbbopt ~/gnomesvn/work $ python bug.py
./file2.html:10: HTML parser error : Misplaced DOCTYPE
declaration
<!-- END Naviscope Javascript --><!DOCTYPE HTML
PUBLIC "-//W3C//DTD HTML
4.0 Tra
                                 ^
<?xml version="1.0"?>
<html>
  <head/>
  <body>
    <div>
<!-- saved from url=(0016)http://intranet/ -->
<!-- BEGIN Naviscope Javascript -->
<!-- END Naviscope Javascript -->
<!-- saved from url=(0027)http://www.agents-tech.co
m/ -->
    </div>
    <div>this is xml</div>
  </body>
</html>

which seems to indicate that at least something is working
.

(note that I'm using the latest SVN for both libxslt and
libxml2)
