<regex>
Defines a template class to parse TR1 Regular Expressions, and several template classes and functions to search text for matches to a regular expression object.
#include <regex>
Remarks
To create a regular expression object, use the template class basic_regex Class or one of its specializations, regex Typedef and wregex Typedef, together with the syntax flags of type regex_constants::syntax_option_type.
To search text for matches to a regular expression object, use the template functions regex_match Function and regex_search Function, together with the match flags of type regex_constants::match_flag_type. These functions return results by using the template class match_results Class and its specializations, cmatch Typedef, wcmatch Typedef, smatch Typedef, and wsmatch Typedef, together with the template class sub_match Class and its specializations, csub_match Typedef, wcsub_match Typedef, ssub_match Typedef, and wssub_match Typedef.
To replace text that matches a regular expression object, use the template function regex_replace Function, together with the match flags of type regex_constants::match_flag_type.
To iterate through multiple matches of a regular expression object, use the template classes regex_iterator Class and regex_token_iterator Class or one of their specializations, cregex_iterator Typedef, sregex_iterator Typedef, wcregex_iterator Typedef, wsregex_iterator Typedef, cregex_token_iterator Typedef, sregex_token_iterator Typedef, wcregex_token_iterator Typedef, or wsregex_token_iterator Typedef, together with the match flags of type regex_constants::match_flag_type.
To modify the details of the grammar of regular expressions, write a class that implements the regular expression traits.
