## Function template split_regex

boost::algorithm::split_regex — Split regex algorithm.

## Synopsis

    // In header: <boost/algorithm/string/regex.hpp>

    template<typename SequenceSequenceT, typename RangeT, typename CharT,
             typename RegexTraitsT>
      SequenceSequenceT &
      split_regex(SequenceSequenceT & Result, const RangeT & Input,
                  const basic_regex< CharT, RegexTraitsT > & Rx,
                  match_flag_type Flags = match_default);

## Description

Tokenize expression. This function is equivalent to C strtok. Input sequence is split into tokens, separated by separators. Separator is an every match of the given regex. Each part is copied and added as a new element to the output container. Thus the result container must be able to hold copies of the matches (in a compatible structure like std::string) or a reference to it (e.g. using the iterator range class). Examples of such a container are `std::vector<std::string>` or `std::list<boost::iterator_range<std::string::iterator>>`

Parameters: |
`Flags` | Regex options
`Input` | A container which will be searched.
`Result` | A container that can hold copies of references to the substrings.
`Rx` | A regular expression
Returns: | A reference to the result
Notes: | Prior content of the result will be overwritten. <simplesectsep></simplesectsep> This function provides the strong exception-safety guarantee
