Powershell - 将 XML 转换为 CSV
[英]Powershell - convert XML to CSV
问题描述
I was able to convert XML to CSV by using the following code:
我能够使用以下代码将 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
It works if the files contain only one root node with one type of child nodes, for example:如果文件仅包含一个具有一种类型子节点的根节点，则它可以工作，例如：
<?xml version="1.0" encoding="UTF-8"?>
<Transaction>
<TXNDETAIL>
<RecordID>02</RecordID>
<SequenceNumber>1</SequenceNumber>

<TransactionDueDate>20170505</TransactionDueDate>
<AdditionalInformation1> </AdditionalInformation1>
<AdditionalInformation2> </AdditionalInformation2>
<HashCode>XXXXXXXX</HashCode>
</TXNDETAIL>
</Transaction>
The output would be like: output 就像：
"RecordID";"SequenceNumber";"TransactionType";"ActionCode";"TransactionID";"SellerCode";"BuyerCode";"TransactionReference";"TransactionDescription1";"TransactionDescription2";"DocumentType";"DocumentNumber";"DocumentDate";"DocumentAmount";"CurrencyCode";"TransactionAmount";"TransactionDueDate";"AdditionalInformation1";"AdditionalInformation2";"HashCode"

Which is great.这是伟大的。

When applying the same code, I get:应用相同的代码时，我得到：
"RecordID";"FileName";"IntermediaryCode";"ActualizationDate";"SequenceNumber";"NumberofRecords";"AmountofRecords"
"01";"001";"19000033";"20170314";"001";"3";"30000"
"02";;;;"1";;
"02";;;;"2";;
"02";;;;"3";;
When I am trying this code instead to retrieve just the head:当我尝试使用此代码而不是仅检索头部时：
#read from file
[xml]$inputFile = Get-Content "c:\pstest\test.xml"
#export xml as csv
$inputFile.Transaction.TXNHEAD.ChildNodes | Export-Csv "c:\pstest\test.csv" -NoTypeInformation -Delimiter:";" -Encoding:UTF8
I get:我得到：
"#text"
"01"
"001"
"19000033"
"20170314"
"001"
"3"
"30000"
What I am trying to achieve, is this output:我想要实现的是这个 output：
"RecordID";"FileName";"IntermediaryCode";"ActualizationDate";"SequenceNumber";"NumberofRecords";"AmountofRecords"
"01";"001";"19000033";"20170314";"001";"3";"30000"

The first object (or Select-Object etc.) in a pipeline defines the header for output no matter if it's file or console output. 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。
What you could do is convert them to csv in two rounds and add it to the same file. 您可以做的是在两轮中将它们转换为csv并将其添加到同一文件中。 Ex: 例如：
$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
You can also combine them like this: 你也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

User2573264's comment only provides a limited amount of data on xml with complex elements and attributes (5 columns of data, where my xml should have 27 columns of data. User2573264 的评论仅提供了 xml 上有限数量的数据，具有复杂的元素和属性（5 列数据，其中我的 xml 应该有 27 列数据。
Guess it is back to the drawing board for me.猜猜它又回到了我的绘图板上。
