30 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 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 summarized in Table 134.
