Hi, I have string line("a_1 = b_1 ( c_2 )") tokenizer< > tok(line); for (tokenizer<>::iterator beg=tok.begin(); beg!=tok.end();++beg) { cout << *beg << endl; } gives me a 1 b 1 c 2 I want to be able to specify delimiters like in strtok so that I get a_1, b_1 and c_2 but couldn't figure out how to specify the tokenizer function. Any suggestions? Regards Rajesh

Here's an example: boost::char_delimiters_separator<char> separator(false, "", " "); boost::tokenizer<> tok(line, separator); Let me know if that helps. Perhaps we should ask John Bandela to include at least one example like this to make things clearer. -- Darin

Perhaps we could drop the first bool argument to simplify things a bit.

Hi, Thanks for your suggestion. The following works: char_delimiters_separator<char> separator(false,"(),= "); but as jeremy suggested, the first arg seems unnecessary. Regards Rajesh --- In Boost-Users@y..., Darin Adler <darin@b...> wrote:
