[oXygen-user] Bug in regular expression negative lookbehind?

[David Sewell]

Platform: oXgen 12.0, build 2010100114
OS X 10.6.4, standalone Java version

Problem:

Given this text:

   It is very cooooooold today.

The regular expression search

   	(?<!o)o

should match only two 'o's, the one after 'c' and the one after 't' (the
regex says "match any o not preceded by 'o'"). Correct?

When I try it, the search matches every 'o'.

Positive lookbehind, and lookahead searches, seem to be okay but I have
not tested very much.
