STINNER Victor <victor.stin...@haypocalc.com> added the comment: If I read correctly '(<(?:(?:[^<>]*)|(?:"[^"]*"))*>)', it is something like (A*|B)*. Regex like (A*)* is *very* slow. It can easily be optimized to A*. Or for (A*|B)* => (A|B)*.
So '(<(?:(?:[^<>]*)|(?:"[^"]*"))*>)' can be optimized to '(<(?:(?:[^<>])|(?:"[^"]*"))*>)'. I hope that it does match the same thing :-) I wrote a library to optimize regular expression, but you are unliky: it doesn't support (?:...) yet :-) https://bitbucket.org/haypo/hachoir/wiki/hachoir-regex ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11665> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
