生产XML文件如下：

   xml version="1.0" encoding="utf-8" ?>
 - < obj >
   < ID > 5  ID >
   < objNm > plane####################1008  objNm >
 - < FDs >
   < FD1 > 4 43 3 32 1 6 0 3 1 2  FD1 >
   < FD2 > 4 43 3 32 1 6 0 3 1 2  FD2 >
   < FD3 > 4 43 3 32 1 6 0 3 1 2  FD3 >
   < FD4 > 4 43 3 32 1 6 0 3 1 2  FD4 >
    FDs >
 - < FD_Clusters >
   < FD_Clusters1 > 4 43 3 32 1 6 0 3 1 2  FD_Clusters1 >
   < FD_Clusters2 > 4 43 3 32 1 6 0 3 1 2  FD_Clusters2 >
   < FD_Clusters3 > 4 43 3 32 1 6 0 3 1 2  FD_Clusters3 >
   < FD_Clusters4 > 4 43 3 32 1 6 0 3 1 2  FD_Clusters4 >
    FD_Clusters >
   < FD_histogram > 17 10 8 5 3 2 1  FD_histogram >
