Re: [Boost-users] [regex] - Bug in boost::regex ??

31 Aug 2006

      Hi,
       Thanks for answering the question. That shows that that is not bug in 
boost::regex. But I have one more thing to ask.  Ofcourse when the 
dependancy on external file is removed boost::regex is working fine. When 
you ran the code with the string directly from the file, did your regex pick 
the second one ? You can certainly think that this is a question not to be 
answered by a busy person like you. You might choose to ignore this 
question. But if you can, please answer this. Also please tell me which 
version of boost library are you using? I am running the code in a linux 
machine and the code i already sent is not picking the second one.

Thanks
Kiran.

Why is the second one not picked ? This was my question.
It is picked for me: I modified your sample program (see below) so that it
actually compiled, and didn't reply on external files, and I see exactly 
the
output expected: everything from the first "Resurfacing" to the last 
"home".
#include "boost/regex.hpp"
using namespace boost;
using namespace std;
#include
#include
#include <iostream>
int main()
{
char buf[10000];
//int fd = open("glass.htm", O_RDONLY);
//int size = read(fd, buf, 10000);
string line = "<!-- saved from url=(0022)http://internet.e-mail -->\n"
"<html><head>\n"
"<title>UGlassIt Fibre-Shelkote Pool Resurfacing for Swimming
Pools</title>\n"
"Home\n"
"Home";
//close(fd);
regex expr("Resurfacing(.|\n)*Home" , boost::regex::icase |
boost::regex::perl);
try
{
sregex_iterator itr(line.begin(), line.end(), expr,
boost::match_not_dot_newline);
sregex_iterator i;
while(itr != i)
{
cout<
