In the picture, I used the expression {[^;]+}; - meaning tag the string formed by any characters until ";" (at least one character) and replace the matching text with "// " followed by the tagged expression, forgetting the last ";". There are a lot of tutorials about regular ...
TheRegExpMatchfunction checks whether any part of the source string matches a regular expression. The result is a Boolean value: TRUE if at least one match is found, FALSE otherwise. Our custom function has 3 arguments - the first two are required and the last one is optional: ...
