Description

Search for a substring matching given regex and format it with the specified format. 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
`Format`	Regex format definition
`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
