What are some advanced regex techniques I can use?

Advanced regex techniques include lookaheads, lookbehinds, and capturing groups. Would you like examples of each?

Yes, please provide an example of a lookahead.

Sure! A lookahead checks for a condition without including it in the match. For example, \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 condition before the match. For instance, (?<=\D)\d matches a digit only if it's preceded by a non-digit.

Can you explain capturing groups?

Capturing groups allow you to extract parts of a match. For example, in (\d+)-(\w+), you can capture the number and the word separately.
