Re: [Boost-users] The boost Tokenizer package: split into a vector of vectors of tokens

Hi,

You might be able to do it using the string_algo find_iterator.

#include <boost/algorithm/string.hpp>

using namespace std;
using namespace boost;

...

typedef find_iterator<string::iterator> string_find_iterator;
string_find_iterator It=make_find_iterator(str1, token_finder(is_space()));

for(int i=0; i<maxi; i++)
for(int j=0; j<maxj; j++)
{
   if(It!=string_find_iterator())
   {
      v[i][j]=*It;
   }
   else
   {
      break;
   }
}

Regards,
Pavol
