Here is a sample:
regex expression(
\\d+);
string text;
// Read the text into the string "text"...
cmatch matchStr;
if(regex_search(text.c_str(), matchStr, expression))
{
for(int i=0; i<matchStr.size(); i++)
{
cout<<"Number :"<<matchStr[i].str()<<endl;
}
}
You can get more samples about the regular expression using in boost document:
