I have a column that's multiline text. I want to match a specific substring and extract it along with everything up until new line. The challenge I'm facing is that there are both "\n" and "\r" and I haven't discovered how to remove the "\r" from my result. Here's the test:

```
    \r
empty
\n
\r\n
basic text
\r
WHATIWANT: - this is cool ! = . a1^@#%\r\n
more lines\r\r\r
\n
\r
\n

```

And the result I want is:

```
WHATIWANT: - this is cool ! = . a1^@#%

```

I tried using:

```
(WHATIWANT:\s.+(.*?)\s+)

```

But get this (can't get rid of the \n and \r):

```
WHATIWANT: - this is cool ! = . a1^@#%\n\r

```
