Question

我想将以下csv分成两个csvs

StartOrder,1,SupplierName,
Line,2,12345,2,5,5.50,
Line,3,12345,3,6,5.20,
Line,4,12345,3,7,1.99,
EndOrder,5,booked as soon as possible to deliver.
StartOrder,6,SupplierName
Line,7,100015,2,5,5.50,
Line,8,100015,3,6,5.20,
Line,9,100015,3,7,1.99,
EndOrder,10,booked as soon as possible to deliver.

为了：

第一个文件

StartOrder,1,SupplierName,
Line,2,12345,2,5,5.50,
Line,3,12345,3,6,5.20,
Line,4,12345,3,7,1.99,
EndOrder,5,booked as soon as possible to deliver.

第二档

StartOrder,6,SupplierName
Line,7,100015,2,5,5.50,
Line,8,100015,3,6,5.20,
Line,9,100015,3,7,1.99,
EndOrder,10,booked as soon as possible to deliver.

我尝试过使用GroupBy但是没有按照我的预期工作。

任何帮助？

Answer 1

这是我用正则表达式做的事情。

    $orders = (get-content -path C:\temp\orders.txt)    
    $orders = [string]::Join("`n",$orders)    # this is to make sure you keep your lines
    $output = [regex]::Matches($orders,'(?s)(StartOrder,(\d{0,}).*?deliver.)') # added regex option S

foreach($c in $output){                
    $order = $c.groups[2].value #order name that will serve as filename
    ""
    $c.groups[0].value # content of order
    $c.groups[0].value  | out-file C:\temp\$order.txt -Force
}

这将创建一个包含所需内容的1.txt和6.txt。

编辑：唯一的问题是它不会保留输入。 - ＆GT; 固定

正则表达式相当简单，有关正则表达式的详细信息：https://regex101.com/r/J0Xsu7/1

这将为您提供带有

的文件1.txt

StartOrder,1,SupplierName,
Line,2,12345,2,5,5.50,
Line,3,12345,3,6,5.20,
Line,4,12345,3,7,1.99,
EndOrder,5,booked as soon as possible to deliver.

这将为您提供带有

的文件6.txt

StartOrder,6,SupplierName
Line,7,100015,2,5,5.50,
Line,8,100015,3,6,5.20,
Line,9,100015,3,7,1.99,
EndOrder,10,booked as soon as possible to deliver.
