Regex to find all matches linewise where text1("abc") is present and text2("xyz") is not present anywhere in each line

Question

Regex to find all matches linewise where text1("abc") is present and text2("xyz") is not present anywhere in each line.

Answer 1

As per your order ;)

Eg.

^(?!.*xyz).*abc.*

should do the trick.

It uses a negative look-ahead to make sure the line doesn't contain the text "xyz", followed by a test any text up to "abc". And to match the whole line, followed by any text.
