I know that libevhtp isn't officially part of libevent yet but maybe someone on this list will have a good solution. Say I want to match the following URIs: /customers/ /customers/1/ /customers/1/transactions/ /customers/1/transactions/13/ If I add matching expressions such as: evhtp_set_cb(htp, "/customers/", customers_cb, "customers"); evhtp_set_regex_cb(htp, "^/customers/([0-9]+)/", customer_cb, NULL); evhtp_set_regex_cb(htp, "^/customers/([0-9]+)/transactions/", transactions_for_customer_cb, NULL); evhtp_set_regex_cb(htp, "^/customers/([0-9]+)/transactions/([0-9]+)/", transaction_for_customer_cb, NULL); I can match the first expression but not get to the second: start = '1', end = '/transactions/13/ What is the best way to get to the 2nd expression '13'? I can re-parse end but then I have multiple places where the code contains the same expression. If you're familiar with Python regular expressions, there is m.group(1), m.group(2), etc to get each match. Thanks, Tom
