regex multiline argh

**sagey** · Jun 22nd, 2006, 11:05 AM

i'm trying to pass google results to get each result

the regex i'm using should get every string that begins with
class=l and ends with nobr

but it only gets 2 results from the html below. the reason is that all other
results contain \n or \r.

when creating the regex object i set mutliline, whcih it thought would sort the problem, but obviously not.

Code:

Regex reg = new Regex("class=l.*?nobr", RegexOptions.Multiline);

i've donea bit of googling and found mentions that . matches anything without a newline and mentions using \s but when i try and use it within my expression it errors and says unrecognised escape sequence.

so what i'd like to know is how to amend my regular expression so that i get back all strings that start with class=l and end siwth nobr, regardless of whether there are newlines or not.

Code:

. matches anything but newline characters.

You are looking for

class=l[.\r\n]*nobr

And you still have to set the MultiLine property as well.
