how to have regex dot match any character including newline?

gnychis · 11-30-2010, 06:02 PM

Hi all,

I am trying to trim a footer that keeps mutating itself via the conversion process to include a variable number of characters and breaklines.

How can I setup my regular expression to have the dot character including any character which includes newline characters?

Thanks!

put this at the very beginning of your regex:

Code:

(?s)

You can also use \s+ or \s* to wrap around a line feed.

thanks for the help!

hmmmm, this seems to be tricky... if I use (?s) all of my text gets selected :P

Here are two examples of what I'm trying to match:

Code:

<hr>
<A name=21></a><i><b>24_</b></i><br>
<i>ΤΖ.Κ. ΡΟΟΥΛΙΝΓΚ</i><br>

Code:

<hr>
<A name=265></a><i>268 ΤΖ. Κ. ΡΟΟΥΛΙΝΓΚ</i><br>

I have tried this regex, which successfully matches the latter but not the prior case

Code:

<hr>\s+.*ΡΟΟΥΛΙΝΓΚ.*<br>

this might be the winner:

Code:

<hr>\n+.*\n?.*ΡΟΟΥΛΙΝΓΚ.*<br>

Probably best not to use .* - it's way too greedy. Try .*? instead. Even that can sometimes have unintended matches, so be sure to review the whole book's matches.
