Re: problems with regular expressions

Well, without more specifics as to when the zero will appear, try this:

print if (/(^\s*|\s+)0/);  # A zero either: starting a line with possi
+ble whitespace in front, or
                                            anywhere in a line with ne
+cessary whitespace in front.

Update: suaveant's suggestion, above, is simpler and works just as well:   print if (/\b0/);
