Question

我无法理解如何为以下类型的flatfiles创建架构，因为标签标识符不在第二个字段上。

我从下面的示例中删除了一些额外的数据，但我的问题几乎就是标记标识符（HDR / ODR和END）前面有一个增量编号。

000001  HDR 0000031001  1DP 
000002  ORD 0000031001  0001
000003  ORD 0000031001  0001
000004  ORD 0000031001  0001
000005  ORD 0000031001  0001
000006  END

我在google上看到的解决方案似乎是基于第一个元素对行进行了争论，假设它对于所有字段都是相同的，但在这种情况下并不起作用。

有没有办法将标签设置为第二个元素？

该文件以制表符分隔。

Answer 1

如果只有那3个标签，并且HDR和END只出现一次，只需创建一个架构，其中你有一个架构，你有三个记录，1个用于HDR，1个用于ORD，可以多次出现，和一个结束。您还必须将Lookahead深度从默认值3更改为0（无限）。

例如，以下模式将正确解析它。

使用标记标识符和标记偏移量来实现目标：

foo
