WebGreedy vs. Non-Greedy Matching. When a special character matches as much of the search sequence (string) as possible, it is said to be a "Greedy Match". It is the normal behavior of a regular expression, but sometimes this behavior is not desired: WebUsing greedy matching, the regular expression engine matches as much text as possible starting with ’ (single quotation mark) and ending with ’ (single quotation mark) which returns "’quick’ brown fox jumps over the ‘lazy’" as the match. However, using non-greedy matching, the regular expression engine matches as little text as ... WebQuantifiers allow you to match their preceding elements a number of times. Quantifiers work in one of two modes: greedy and non-greedy (lazy). When quantifiers work in the greedy mode, they are called greedy quantifiers.
