What are some advanced regex techniques I can use?

You can use lookaheads, lookbehinds, and named groups for more complex pattern matching. Would you like examples?

Yes, please provide an example of a lookahead.

Sure! A lookahead can be used to find a pattern only if it's followed by another pattern. For instance, \d(?=\D) matches a digit only if it's followed by a non-digit.

That's interesting! How about a lookbehind?

A lookbehind checks for a pattern that precedes another pattern. For example, (?<=\D)\d matches a digit only if it's preceded by a non-digit.

Can you explain named groups?

Named groups allow you to assign a name to a capturing group for easier reference. For example, (?<year>\d{4}) captures a four-digit year and you can refer to it as year later.
