我正在使用具有以下架构的Dataframe。这基本上是一个XML文件，我已将其转换为Dataframe以进行进一步处理。我尝试提取 _Date 列，但看起来发生了某种类型不匹配的情况
dplyr我需要提取 _Date 列，但是它会抛出以下错误
df1.printSchema
|-- PlayWeek: struct (nullable = true)
| |-- TicketSales: array (nullable = true)
| | |-- element: struct (containsNull = true)
| | | |-- PlayDate: array (nullable = true)
| | | | |-- element: struct (containsNull = true)
| | | | | |-- BoxOfficeDetail: array (nullable = true)
| | | | | | |-- element: struct (containsNull = true)
| | | | | | | |-- VisualFormatCd: struct (nullable = true)
| | | | | | | | |-- Code: struct (nullable = true)
| | | | | | | | | |-- _SequenceId: long (nullable = true)
| | | | | | | | | |-- _VALUE: double (nullable = true)
| | | | | | | |-- _SessionTypeCd: string (nullable = true)
| | | | | | | |-- _TicketPrice: double (nullable = true)
| | | | | | | |-- _TicketQuantity: long (nullable = true)
| | | | | | | |-- _TicketTax: double (nullable = true)
| | | | | | | |-- _TicketTypeCd: string (nullable = true)
| | | | | |-- _Date: string (nullable = true)
| | | |-- _FilmId: long (nullable = true)
| | | |-- _Screen: long (nullable = true)
| | | |-- _TheatreId: long (nullable = true)
| |-- _BusinessEndDate: string (nullable = true)
| |-- _BusinessStartDate: string (nullable = true)
任何帮助都将不胜感激。
