PHP Regex: Pattern to match "url()" -

-

यह Regex: 

  $ pattern = '/ url \ (([^)] +) \) / ';

url (...) में सीएसएस फ़ाइलों के बीच सब कुछ मेल खाता है। समस्या: यदि उद्धरण हैं, तो इस तरह: url ('...') , वे लौटे हुए वाक्यांशों में भी होते हैं।

उद्धरण चिह्नों के बिना एक वाक्यांश कैसे वापस जाना , यदि कोई हो? 

  url \ (['']] ([^] ] +?) [']]? \)

इसे आपके लिए करना चाहिए। बनाओ ' या ' वैकल्पिक।

देखें डेमो।

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
