Powershell - 将XML转换为CSV

标签： xml powershell csv

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，则可以正常工作，例如：

<?xml version="1.0" encoding="UTF-8"?>
<Transaction>
    <TXNDETAIL>
        <RecordID>02</RecordID>
        <SequenceNumber>1</SequenceNumber>

        <CurrencyCode>949</CurrencyCode>
        <TransactionAmount>10000</TransactionAmount>
        <TransactionDueDate>20170505</TransactionDueDate>

        <TransactionAmount>10000</TransactionAmount>
        <TransactionDueDate>20170505</TransactionDueDate>
        <AdditionalInformation1> </AdditionalInformation1>
        <AdditionalInformation2> </AdditionalInformation2>
        <HashCode>XXXXXXXX</HashCode>
    </TXNDETAIL>
    <TXNDETAIL>
        <RecordID>02</RecordID>
        <SequenceNumber>3</SequenceNumber>
        <TransactionType>01</TransactionType>

        <TransactionReference> </TransactionReference>
        <TransactionDescription1> </TransactionDescription1>
        <TransactionDescription2> </TransactionDescription2>
        <DocumentType>01</DocumentType>
        <DocumentNumber>XXXXXXXXXXX</DocumentNumber>
        <DocumentDate>20170301</DocumentDate>
        <DocumentAmount>10000</DocumentAmount>
        <CurrencyCode>949</CurrencyCode>
        <TransactionAmount>10000</TransactionAmount>
        <TransactionDueDate>20170505</TransactionDueDate>
        <AdditionalInformation1> </AdditionalInformation1>
        <AdditionalInformation2> </AdditionalInformation2>
        <HashCode>XXXXXXXX</HashCode>
    </TXNDETAIL>
</Transaction>

输出如下：

    "RecordID";"SequenceNumber";"TransactionType";"ActionCode";"TransactionID";"SellerCode";"BuyerCode";"TransactionReference";"TransactionDescription1";"TransactionDescription2";"DocumentType";"DocumentNumber";"DocumentDate";"DocumentAmount";"CurrencyCode";"TransactionAmount";"TransactionDueDate";"AdditionalInformation1";"AdditionalInformation2";"HashCode"

"02";"2";"01";"01";"17500515622017001";"2200919TRY";"KOCZER";"";"";"";"01";"XXXXXXXXXXX";"20170301";"10000";"949";"10000";"20170505";"";"";"XXXXXXXX"

哪个好。

然而，输入文件实际上有一个＆＃34;标题行＆＃34;信息，TXNHEAD标签

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

当应用相同的代码时，我得到：

    "RecordID";"FileName";"IntermediaryCode";"ActualizationDate";"SequenceNumber";"NumberofRecords";"AmountofRecords"
"01";"001";"19000033";"20170314";"001";"3";"30000"
"02";;;;"1";;
"02";;;;"2";;
"02";;;;"3";;

当我尝试使用此代码时，只需检索头部：

#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

我明白了：

"#text"
"01"
"001"
"19000033"
"20170314"
"001"
"3"
"30000"

我想要实现的是这个输出：

"RecordID";"FileName";"IntermediaryCode";"ActualizationDate";"SequenceNumber";"NumberofRecords";"AmountofRecords"
"01";"001";"19000033";"20170314";"001";"3";"30000"
"RecordID";"SequenceNumber";"TransactionType";"ActionCode";"TransactionID";"SellerCode";"BuyerCode";"TransactionReference";"TransactionDescription1";"TransactionDescription2";"DocumentType";"DocumentNumber";"DocumentDate";"DocumentAmount";"CurrencyCode";"TransactionAmount";"TransactionDueDate";"AdditionalInformation1";"AdditionalInformation2";"HashCode"
"02";"1";"01";"01";"17500515552017001";"2200919TRY";"KOCZER";"";"";"";"01";"XXXXXXXXXXX";"20170301";"10000";"949";"10000";"20170505";"";"";"XXXXXXXX"
"02";"2";"01";"01";"17500515622017001";"2200919TRY";"KOCZER";"";"";"";"01";"XXXXXXXXXXX";"20170301";"10000";"949";"10000";"20170505";"";"";"XXXXXXXX"
"02";"3";"01";"01";"17500515972017001";"2200919TRY";"KOCZER";"";"";"";"01";"XXXXXXXXXXX";"20170301";"10000";"949";"10000";"20170505";"";"";"XXXXXXXX"

我做错了什么？

2 个答案:

答案 0 :(得分：1)

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

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。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

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
