Use Regular Expression with Poco

[ShrewMouse]

Hi All,

When I use regular expression to extract a string, it look like return the first match of the target string:
RegularExpression re(pattern, options);
std::string returnString;
int returnMatch = re.extract(line, returnString);

So if returnMatch >= 2 , how can I get the string of second match ?

Thanks for any helps,
Dat

You have to do it by hand. See the source code for extract(), which simply calls match(). Then call the match() function returning the result in a vector (MatchVec), and extract the string yourself (substr()).
