Question

I m 采用Boost。 Reg Reg achieve achieve search search search then left left left left

string s1;
string s2;
who | sort

After this s1 should be "who" and s2 shoudl be "sort".
If I remember good, it was posible in Python, how can I do it using regular expressions in Boost ?

谢谢。

Answer 1

#include <boost/algorithm/string.hpp>
std::vector<std::string> strs;
boost::split(strs, "string to split", boost::is_any_of("|"));

C++中的插图?

Answer 2

这里的样本短:

#include <iostream>
#include <boost/regex.hpp>

int main()
{
  // expression
  boost::regex exrp( "(.*)\|(.*)" );
  boost::match_results<std::string::const_iterator> what;
  // input
  std::wstring input = "who | sort";
  // search
  if( regex_search( input,  what, exrp ) ) {
    // found
    std::string s1( what[1].first, what[1].second );
    std::string s2( what[2].first, what[2].second );
  }

  return 0;
}
