RegEx: dot operator to match line break?

[owilsky]

Hi,

is it possible to get the dot operator to match a line break? Normally . means [^\n]

What I need:

Get all text from first line break until two line breaks, that means get all lines beginning from the second line until there is an empty line.

Something like this: \r\n(.+?)\r\n *\r\n

Unfortunately I only get the first line because (.+?) only goes to the first line break.

I know that this is perl compatible, but most regex engines have some kind of switches.

Are there any?

I use the latest beta (3.2.1.10)

Thanks,

Oliver

My mind is pretty simple when it comes to programming and usually I cant grasp the point very quickly, but this is just confusing to no end

i can barely read this

The line break in autoit is @CRLF

example: msgbox(0,"","Line" & @CRLF & "Break")

@CRLF is a combined Carriage return (Chr(13)) and a Line feed, (Chr(10)). Keep in mind based upon what you are using that you can use either of them separately. The most common one for linebreaks is @LF. You can also use @CR.

Whats the difference anyway? my friend used to complain about me using @CRLF instead of @CR and @LF but he never explained it

The descriptions are terrible in the helpfile

@CR Carriage return, Chr(13); sometimes used for line breaks.

@CRLF = @CR & @LF ;occasionally used for line breaks.

@LF Line feed, Chr(10); typically used for line breaks.

It cracks me up at how simple they are too...

@CRLF is two bytes in length. @LF is one byte in length and @CR is also one byte in length. @LF is more commonly used and therefore is the best choice because it is both small in size and commonly used.

oh ok but my harddrive has 73863176192 bytes so really it doesntmake a difference

but oh well ill start using lf from now on!

\r\n is windows standard so unsure where you get only \n from?

If you want your pattern to match multiline as one, then start the pattern with this group "(?s)". That will make the dot token match the remainder of the regex pattern including newlines.

EOL Standards

@CRLF used by Windows.

@LF used by Linux\Unix.

@CR used by Macintosh.

This was the info I needed. Thanks a lot!

I know that there is @CRLF etc, but that does not help me with regex.

I also know that on windows I have to use \r\n instead of only \n. That was only an example.

The informataion I was looking for was the "(?s)".

Thanks again!
