Hi,

Ive tried that, however been a complete newbie to boost im probably still 
missing something obvious. Heres the test code so far

#include <stdlib.h>
#include <iostream>
#include <string>
#include <boost/regex.hpp>
using namespace std;
int main (int argc, char *argv[])
{
string uri ("slx://account/12345");
boost::regex re ("\\w+");
boost::cmatch what;
if (boost::regex_match(uri.c_str(), what, re))
{
cout << what[0] << endl;
cout << what[1] << endl;
cout << what[2] << endl;
}
else
{
cout << "nowt matched" << endl;
}
return 0;
}
