Exclude delimiter from regular expression

I'm pretty new at regular expressions. For a string like this:

[quote="Username;123456]

I have created this regular expression:

%\[quote=("|&\#039;|"|\'|)([^\r\n]*?)[^;](\d+)\]%s

This puts out 3 matches:

  • "
  • Username;
  • 23456

Why is [^;] not negating the semicolon, but instead removing one digit and how can I fix this? Thanks.

Solution

  • Your ([^\r\n]*?) can eat the ;, so the [^;] is free to take a digit (because it will match anything except the ;).

    You probably wanted ; (without [^ ]:

    %\[quote=("|&\#039;|"|\'|)([^\r\n]*?);(\d+)\]%s
