Re: regular expression to exclude a phrase

zhihuali schreef:

I was wondering if there's a way to specify "not including this
phrase" in perl regexp.
Like such two strings:
axbcabcd
axbcacbd

If I say "not including the letter a or the letter b" (=~/[^a^b]/)
then neither of them will be matched.

The [^a^b] doesn't mean what you think it means. The "^" only has a
special meaning at the start.


However now I want to say "not
including the phrase 'ab'", then the string 2 should be matched.
But I can't figure out how to specify the second condition by regexp.
Could anyone help me?

There are many ways to do this, but let's play it simple:

if ( m/ab/ ) {
# do nothing
}
else {
# do something
}
