Well ,john it just wont , this is my RE :
(?:(<\s*LI[^>]*>(?:<[^>]*>)*\s*<\s*A\s+HREF[^>]*>)([^<>]*?)(?:<[^>]*>)
*(<\s*/A.*?>))|(?:(<\s*A\s+HREF[^>]*>)(?:<[^>]*>)*([^<>]*?)(?:<[^>]*>)
*(\s*<\s*/A\s*>(?:<[^>]*>)*<\s*/H.?\s*>))
when I use this format string :
?1\t$2\n:$5\n
it works great , since its a boolean , either A or B
but when I try :
(?1\t$2\n)(?2$5\n)
or :
?1\t$2\n?2$5\n
I get only the first expression , I am probably doing something
wrong , but what ?
the code behind this is :
while(boost::regex_search(start, end, results, expression,
flags))
{
std::string str;
str.assign ( boost::regex_format ( results , fmt ,
boost::format_all ) );
std::cout << str ;
start = results[0].second;
}
I would appreciate your help
thanks
