objective c - NSRegularExpression, select part of a string -

given string this:

seat 2: pet21 ($1.98 in chips)

in php can select part of regex using parentheses in regex, this:

seat ([0-9]+): (.{1,12}) .[$|€|£]([0-9]+\.?[0-9]{0,2}) in chips.

this selects seat number, user id , amount of chips:

array ( [0] => array ( [0] => seat 1: s@pphir ($0.83 in chips) [1] => seat 2: pet21 ($1.98 in chips) [2] => seat 3: derphurp ($2.76 in chips) [3] => seat 4: -m-a-r-k-qaz ($0.92 in chips) [4] => seat 5: rolle55 ($2.45 in chips) [5] => seat 6: sanderdecler ($2 in chips) ) [1] => array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 ) [2] => array ( [0] => s@pphir [1] => pet21 [2] => derphurp [3] => -m-a-r-k-qaz [4] => rolle55 [5] => sanderdecler ) [3] => array ( [0] => 0.83 [1] => 1.98 [2] => 2.76 [3] => 0.92 [4] => 2.45 [5] => 2 ) )

is there way similar in objective-c nsregularexpression

edit: far i've got this:

nsregularexpression *regex = [nsregularexpression regularexpressionwithpattern:@"seat [0-9]+: (.{1,12}) .[$|€|£][0-9]+\.?[0-9]{0,2} in chips." options:0 error:nil]; (nstextcheckingresult *result in [regex matchesinstring:history options:nsmatchingreportcompletion range:nsmakerange(0, history.length)]) { }

you want utilize firstmatchinstring:options:range: method of nsregularexpression, returns nstextcheckingresult. want utilize rangeatindex: method of nstextcheckingresult range of each submatch. can pass range substringwithrange: method of original nsstring text of submatch.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
