A sequence of characters matched by a particular marked sub-expression.
An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression.
The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

int std::sub_match::compare | ( | const sub_match & | __s | ) | const [inline] |
Compares this and another matched sequence.
s | Another matched sequence to compare to this one. |
<0 | this matched sequence will collate before s . |
=0 | this matched sequence is equivalent to s . |
<0 | this matched sequence will collate after s . |

Gets the matching sequence as a string.
This is the implicit conversion operator. It is identical to the str() member function except that it will want to pop up in unexpected places and cause a great deal of confusion and cursing from the unwary.
