Regex: Match double single quote inside string

I want a regex that will match for example 'panic can''t happen' as panic can''t happen. Double single quotes are just allowed if they're next to each other, 'panic can't' happen' sgould be divided into two strings, panic can and happen.

I got \'[^\']*[\'\']?[^\']\' so far but it won't work as expected.

Thanks!

Solution

  • You can try the following:

    '(?:[^']+|'')+'
    • ': Matches a literal '.
    • [^']+: Matches one or more characters which are not '.
    • '': Matches double ''.
    • (?:[^']+|'')+: Matches one or more occurrences of the preceding two patterns.
    • ' matches the closing '.
