The metacharacters listed in the following table are anchors. Back to top Grouping constructs delineate subexpressions of a regular expression and typically capture substrings of an input string.Grouping constructs include the language elements listed in the following table. Back to top A quantifier specifies how many instances of the previous element (which can be a character, a group, or a character class) must be present in the input string for a match to occur.
