Subject: [Boost-users] [Regex] : Unknown character sequence.

Hi,

   I'm new to regex.  This is basically what I was trying.

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

int main()
{
    std::string input = "sand._12";
   boost::regex reg(".*\._[0-9]+");
 
 If you're trying to escape the "." you probably also need to escape the "\" by using "\\". It is a C string after all.
