Synopsis

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


template<typename OutputIteratorT, typename RangeT, typename CharT, 
         typename RegexTraitsT> 
  OutputIteratorT 
  erase_regex_copy(OutputIteratorT Output, const RangeT & Input, 
                   const basic_regex< CharT, RegexTraitsT > & Rx, 
                   match_flag_type Flags = match_default);
template<typename SequenceT, typename CharT, typename RegexTraitsT> 
  SequenceT erase_regex_copy(const SequenceT & Input, 
                             const basic_regex< CharT, RegexTraitsT > & Rx, 
                             match_flag_type Flags = match_default);

Description

Remove a substring matching given regex from the input. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.

	Note
	The second variant of this function provides the strong exception-safety guarantee

Parameters:

`Flags`	Regex options
`Input`	An input string
`Output`	An output iterator to which the result will be copied
`Rx`	A regular expression

Returns:

An output iterator pointing just after the last inserted character or a modified copy of the input
