Regex ignoring new lines

Im trying to write a regular expression to break apart a string, however it seems to ignore new lines.

What Im trying to do is:-
diag
So, Ive done the following:-
`\[(b|i|size|code|color|center|quote|url|img)=?(.*?)\](.+?)\[/\1\]`

Open in new window


Which works great with this test data:-
Sample 1
However if I include some new lines inbetween the tags, its ignored completly:-
Sample 2
Ive looked around, and from what I understand it should be including the new lines with the `\[(b|i|size|code|color|center|quote|url|img)=?(.*?)\](.+?)\[/\1\]`

Anyone know how I can change the "(.+?)\" to include new lines?

Use "single-line mode". You haven't specified which language you are using, but most likely you simply need to add an "s" to the end of your pattern--outside of the delimiters:

`\[(b|i|size|code|color|center|quote|url|img)=?(.*?)\](.+?)\[/\1\]`s

Open in new window


By default, a dot will never match a newline. In order to change this, you enable single-line mode.

Do not confuse single-line mode with "multi-line mode", as many people do. Multi-line mode affects ^ and $, and does nothing to the behavior of dot.

It was php, but that worked great, thank you :-)
