This page is for those who have mastered the basics and are ready to move on to more complex regex linking techniques.
Group references are a powerful tool in advanced regex linking. They allow you to reference backreferences within a match.
Here is an example of a regex that uses group references:
(?<regex>pattern).*<1>pattern
This regex will match the string "abc" and capture "abc" as group 1. The backreference <1> can then be used to match the string "abc".
Positive lookahead assertions are a way to match a pattern without consuming it. They are useful for advanced regex linking techniques.
Here is an example of a regex that uses positive lookahead assertions:
(?=pattern)regex
This regex will match the string "abc" and the lookahead assertion will match the first letter "a".
Conditional statements are a powerful tool in advanced regex linking. They allow you to execute different actions based on the outcome of a match.
Here is an example of a regex that uses conditional statements:
(if pattern)then{regex}else{regex}
This regex will match the string "abc" and the "then" block will be executed if it matches, otherwise the "else" block will be executed.
