Assuming that C++ and Boost Regex have a similar structure and functionality, the difference between regex_match
and regex_search
is explained here:
The
regex_match()
algorithm will only report success if the regex
matches the whole input, from beginning to end. If the regex matches
only a part of the input,regex_match()
will return false. If you want
to search through the string looking for sub-strings that the regex
matches, use theregex_search()
algorithm.
