标题: 如何随机获取服务器响应数组值并保存成参数？
lr_xml_get_values函数可以取到ExamID_ALL数组。请问如何随机获取其中之一，并保存到{ExamID}中供下次web service call调用？
web_service_call(...);

NumOfValues = lr_xml_get_values("XML={response}",
"Query=/Envelope/Body/SearchResponse/ResultSet/*/value[16]",
"ValueParam=ExamID_ALL",
"SelectAll=yes", LAST);

srand( time(NULL) );
i = rand() % (NumOfValues + 1);
sprintf( E_examid, "Retrieved value %d : {ExamID_ALL_%d}", i + 1, i + 1 );
lr_output_message(lr_eval_string(E_examid));

lr_output_message(lr_eval_string("firstExamID = {ExamID_ALL_1}"));

soap_request("..., "SOAPEnvelope=..."
"<requestedProcedureID xmlns=\"\">{ExamID}</requestedProcedureID>"
"Snapshot=t21.inf", "ResponseParam=response",
LAST);

看得晕，我猜是不是应该用
lr_save_string(ExamID, ExamID_ALL [ i ] );

标题: 搞定了，共享下：）
int i = 0, NumOfValues = 0;
char E_examid[64];

NumOfValues = lr_xml_get_values("XML={response}",
   "Query=/Envelope/Body/SearchResponse/ResultSet/*/value[16]",
   "ValueParam=ExamID",
   "SelectAll=yes", LAST);

srand( time(NULL) );

i = rand() % NumOfValues + 1;

sprintf(E_examid, "{ExamID_%d}", i);

sprintf(E_reportid, "{ReportID_%d}", i);

lr_save_string(lr_eval_string(E_examid), "ExamID");

lr_output_message(lr_eval_string("{ExamID}"));
