28 Regular expressions library [re]

This Clause describes components that C++ programs may use to perform operations involving regular expression matching and searching.

The following subclauses describe a basic regular expression class template and its traits that can handle char-like ([strings.general]) template arguments, two specializations of this class template that handle sequences of char and wchar_t, a class template that holds the result of a regular expression match, a series of algorithms that allow a character sequence to be operated upon by a regular expression, and two iterator types for enumerating regular expression matches, as described in Table [tab:re.lib.summary].
