Powershell - 将XML转换为CSV

7 xml csv powershell

我可以使用以下代码将XML转换为CSV: 

    #read from file
[xml]$inputFile = Get-Content "c:\pstest\test.xml"
#export xml as csv
$inputFile.Transaction.ChildNodes | Export-Csv "c:\pstest\test.csv" -NoTypeInformation -Delimiter:";" -Encoding:UTF8

如果文件只包含一个具有一种子节点类型的根节点,则它可以工作,例如:

<?xml version="1.0" encoding="UTF-8"?>

我究竟做错了什么？

Fro*_* F. 2

管道中的第一个对象（或Select-Object等）定义输出的标头，无论它是文件还是控制台输出。

您可以做的是将它们分两轮转换为 csv 并将其添加到同一文件中。前任：

$inputFile.Transaction.TXNHEAD | ConvertTo-Csv -NoTypeInformation -Delimiter ";" | Set-Content -Path "c:\pstest\test.csv" -Encoding UTF8
$inputFile.Transaction.TXNDETAIL | ConvertTo-Csv -NoTypeInformation -Delimiter ";" | Add-Content -Path "c:\pstest\test.csv" -Encoding UTF8

您还可以像这样组合它们：

$inputFile.Transaction.TXNHEAD, $x.Transaction.TXNDETAIL |
ForEach-Object { $_ | ConvertTo-Csv -NoTypeInformation -Delimiter ";" } |
Set-Content -Path "c:\pstest\test.csv" -Encoding UTF8
