Thread: boost.regex not working?

I've read the manual. I've checked the example. But I don't get it.

Code:

    boost::regex expres("([0-9]+)");
    boost::cmatch matches;
    boost::regex_match(buff.c_str(), matches, expres);

    for (unsigned int i = 1; i < matches.size(); i++)
     {
        std::string match(matches[i].first, matches[i].second);
        cout << (match + ";") << endl;
     }

Code above is not working. I get nothing on cout.

buff is a string retrieved by curl from www.google.com. It contains the code. And there are numbers in it.

Hmm, never found this in examples.
It seems like .+([0-9]+?).+ does the trick.
I thought this would work the normal way, as in php's preg, if you pass it some expression, it will look for a match of that expression somewhere in the string, not an exact match of the expression to the string

Use regex_search(), not regex_match().
