boost::Regex的问题.....

C/C++ code

#include <iostream> #include <boost/regex.hpp> int main( int argc, char* argv[] ){    char *buf="c.addCity(\"4476\",\"北京市朝阳区\")cur.addBoard(new Board(\"CN\",\"3478\",\"浙江\")";     boost::regex exampleregex("(\"[^0-9a-zA-Z,]*\")");    boost::cmatch result;     if(boost::regex_search( buf, result, exampleregex ))     {         std::cout << result << std::endl;     }     return 0; }

以上代码为何只能输出第一个中文字符串："北京市朝阳区"；
第二个为什么查找不出来？
难道是查找到一个就停止吗，那如何才能使其继续查找？

[解决办法]

C/C++ code

#include <iostream> #include <boost/regex.hpp> int main( int argc, char* argv[] ){    char *buf="c.addCity(\"4476\",\"北京市朝阳区\")cur.addBoard(new Board(\"CN\",\"3478\",\"浙江\")";     boost::regex exampleregex(".*(?:,|\\()(\"[^0-9a-zA-Z,]*\")\\).*(?:,|\\()(\"[^0-9a-zA-Z,]*\")\\)");    boost::cmatch result;     if(boost::regex_match( buf, result, exampleregex ))     {         for (int i = 0; i < result.size(); ++i)            std::cout << result[i].str() << std::endl;     }     return 0; }

C/C++ code#include <iostream> #include <boost/regex.hpp> #include <string>using namespace std;int main( int argc, char* argv[] ){    string buf="c.addCity(\"4476\",\"北京市朝阳区\")cur.addBoard(new Board(\"CN\",\"3478\",\"浙江\")";     boost::regex exampleregex("\"[^0-9a-zA-Z,]*\"");    boost::cmatch result;     string::const_iterator begin = buf.begin();    string::const_iterator end = buf.end();    while (boost::regex_search(begin, end, result, exampleregex ))     {         cout << string(result[0].first, result[0].second) << endl;        begin = result[0].second;    }     return 0; }
