Re: Regex with newline

Update: Thanks for the help. It was the return character. This works:

$text =~ s|\r\n\r\n|<br /><br />|sg;

Note that thabenksta's example does not include the `'/s'`. You do not need it and you obscure its meaning and usefulness when you use it reflexively just because you are working with multiple lines. `'/s'` simply allows '.' to match line break characters. It has no other effect on the ability of your regex to work with multiple lines.	[reply] [d/l] [select]

I know this was an old post but it answered a question for me however it also brought up another one....is there any way to limit the number of tags to only two..that is, no matter how many times a user presses the enter key paragraphs are separated by two spaces(and no more than two). Thanks	[reply]

Yes. For example: `$text =~ s%(?:\r\n){2,}%<br /><br />%g;` [download]	[reply] [d/l]
