There is the following text:

QR-Code:какой-то текст QR-Code:еще какой-то текст QR-Code:текст для кода QR-Code:текст для кодирования scanned 6 barcode symbols from 6 images

you need to extend the values ​​of QR codes between the "QR Code:" and the symbol of the beginning of a new line.

I try the regular expression of type:

 QR-Code:(.*)\n

does not work. tell me how to make it right?

  • Shouldn't slash in / n be reversed? (A typo in the most tried regular season or only in this question?) - Maxim Kamalov
  • just a typo in the question. QR-Code: (. *) \ N - r00xus
  • Do you have multiline text there? Before every QR - line feed? - shoorick
  • Yes. multiline text. before every QR-Code a new line - r00xus
  • And what language? Specify. - dlarchikov
