Import Stata:导入带有不一致分隔符的.txt

我有一个带有相对奇怪分隔符的.txt文件。数据如下所示：

|ABC4|,|Name1|,|NameRaw1|,|y|,|XY1|,10000.0,|     |,|FOURTH QUARTER REPORT|,||
|ABC5|,|Name2, extraname|,|NameRaw2|,,|XY2|,266539.0,|pac  |,|MID-YEAR REPORT|,||
|ABC6|,|Name3|,|NameRaw3|,|y|,|X,Y3|,60000.0,|name |,|YEAR-END REPORT|,|XYZ|

因此，有一个问题是，有些变量没有管道，比如第六个变量，它只是一个没有管道的量，而有些变量只有在它们为空时才没有管道，比如第四个变量，它是

，

或

，|y |，

。有些变量也有逗号，所以我不能用逗号作为分隔符。所以基本上有两个问题：

分隔符是逗号，但逗号也显示在字符串值中

有些变量在管道内，有些不在管道内，有些仅在它们不为空时才在管道内

---

我正在寻找一种方法来解决这个问题。有人知道怎么做吗？

如果完整的数据集比这个例子更混乱，我真的不想知道。但这似乎有点道理
