I need a function/plugin to extract only unnecessary text from lines

chciałbym aby taką operację mógł wykonać, mam taki plik wiersze w pliku 
karolsieczko1:Kaaarolek24 | Dostępny transfer = 50 MB | Punkty = 1000
darek221:Darek221 | Dostępny transfer = 270,8 MB | Punkty = 1000
tomzdw:sztepci0 | Dostępny transfer = 127,41 MB | Punkty = 1000
rpiecuch:ra3f0p6 | Dostępny transfer = 50 MB | Punkty = 1000
morgrim9:norekk123 | Dostępny transfer = 50 MB | Punkty = 1000

and I would like to receive such a file with the words removed
this is what it would look like:

karolsieczko1:Kaaarolek24
darek221:Darek221
tomzdw:sztepci0
rpiecuch:ra3f0p6

Manually deleting such texts takes days, so my question is: is there a plugin, command, or other solution? Sorry for the inquiries, but I’m completely unfamiliar with such processes. Best regards.

@Ragnar-Lodbrok ,

My suggestion: Use the Search > Replace menu action (or Ctrl+H as the default shortcut):

FIND WHAT = ^(\w+:\w+)?.*$(\R)?
REPLACE WITH = ?1$1$2
SEARCH MODE = Regular Expression

then use REPLACE ALL button

The FIND WHAT puts any xyz123:abc987 at the beginning of a line into memory group #1, skips over the rest of the line, and puts the newline sequence in group#2.
The REPLACE with will replace that entire line with just the contents of group#1 followed by group#2 (so the xyz123:abc987 and newline) IF the xyz123:abc987 exists; if it DOESN’T exist, it will replace the entire line with nothing (hence deleting the line)

I believe this does what you want.
