如何使用Spark中的数据框从嵌套JSON中选择数据。 从下面的示例JSON中，我想从Array中的Array中选择数据。

"xyz01": [

        {
          "@SEGMENT": "1","POS": "00001","MEN": "10.000","xyz05": [
            {            
              "CHL": "DIRECT","BET": "54545"
            },{
              "@SEGMENT": "1","CHL": "INDIRECT","TRG": "778787",}
            ]
        },{
          "@SEGMENT": "1","POS": "00002","MENGE": "4354354","xyz05": [
            {
              "@SEGMENT": "1","ALCKZ": "+","CHL": "DIRECT",},"TRG": "3434343"
            }
          ]
         };      
         ]

必需的输出。

POS CHL

000001直接

000001间接

000002直接

000002间接
