http://xmlsoft.org/news.html lists a bugfix for 2.6.32 about "regexp bug
with '.' (Andrew Tosh)". The full entry from the ChangeLog is

        xmlregexp.c: apply patch from Andrew Tosh to fix behaviour
                  when '.' is used in a posCharGroup
        
That should explain the difference.
