c# - Can't resolve namespace while parsing a XML wih XDocument -

-

I need some help in parsing this XML.

I get the following string and I need to get the value of "MensajeError"

I have made it on physical tags but I do not manage to parse under XML 

  var xDocument = XDocument.Parse (resultado) can; X-namespace soap = "http://schemas.xmlsoap.org/soap/envelope/"; Var xElements = xDocument.Descendants (Soapenby + "Body"). First ()

The tag that I tried to parse "" failed. I just need to retrieve the "Mentass Aror" tag

Thanks!

You can just use the local name: 

  Var nodeValue = XDocument.Parse (resultado). Dscendants () First (n = & gt; n.Name.LocalName == "MensajeError"). value; // nodeValue = "error1"

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...
