使用Powershell将具有名称空间的XML转换为CSV [英] Converting XML with namespaces to CSV using powershell

问题描述

我有这个XML文件:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:BOX xmlns="urn:loc.gov:item" 
         xmlns:ns2="urn:loc.gov:box" 
         xmlns:ns3="http://www.example.com/inverter" 
         xmlns:ns4="urn:loc.gov:xyz">
    <ns3:Item>
        <Description>ITEM1</Description>
        <PackSizeNumeric>6</PackSizeNumeric>
        <ns2:BuyersItemIdentification>
            <ID>75847589</ID>
        </ns2:BuyersItemIdentification>
        <ns2:CommodityClassification>
            <CommodityCode>856952</CommodityCode>
        </ns2:CommodityClassification>
        <ns2:AdditionalItemProperty>
            <Name>Weight</Name>
            <Value>0</Value>
        </ns2:AdditionalItemProperty>
        <ns2:AdditionalItemProperty>
            <Name>Tare</Name>
            <Value>0</Value>
        </ns2:AdditionalItemProperty>
        <ns2:ManufacturerParty>
            <ns2:PartyIdentification>
                <ID>847532</ID>
            </ns2:PartyIdentification>
        </ns2:ManufacturerParty>
    </ns3:Item>
    <ns3:Item>
        <Description>ITEM2</Description>
        <PackSizeNumeric>10</PackSizeNumeric>
        <ns2:BuyersItemIdentification>
            <ID>9568475</ID>
        </ns2:BuyersItemIdentification>
        <ns2:CommodityClassification>
            <CommodityCode>348454</CommodityCode>
        </ns2:CommodityClassification>
        <ns2:AdditionalItemProperty>
            <Name>Weight</Name>
            <Value>0</Value>
        </ns2:AdditionalItemProperty>
        <ns2:AdditionalItemProperty>
            <Name>Tare</Name>
            <Value>0</Value>
        </ns2:AdditionalItemProperty>
        <ns2:ManufacturerParty>
            <ns2:PartyIdentification>
                <ID>7542125</ID>
            </ns2:PartyIdentification>
        </ns2:ManufacturerParty>
    </ns3:Item>
</ns3:BOX>

我正在尝试将其转换为CSV文件.

I'm trying to convert it to a CSV file.

我得到的内容:

[xml]$inputFile = Get-Content test.xml

然后我导出为CSV:

$inputfile.BOX.childnodes | Export-Csv "Stsadm-EnumSites.csv" -NoTypeInformation -Delimiter:";" -Encoding:UTF8

我得到了 Description 和 PackSizeNumeric 字段，但是没有其他字段:

I get the Description and PackSizeNumeric fields but not the other fields which are in :

"Description";"PackSizeNumeric";"BuyersItemIdentification";"CommodityClassification";"AdditionalItemProperty";"ManufacturerParty"
"ITEM1";"6";"System.Xml.XmlElement";"System.Xml.XmlElement";"System.Object[]";"System.Xml.XmlElement"
"ITEM2";"10";"System.Xml.XmlElement";"System.Xml.XmlElement";"System.Object[]";"System.Xml.XmlElement"

哪种方法是获取其他命名空间中包含的字段的最佳方法?

Which is the best way to obtain the fields that are contained in other namespaces?

我想得到这个

"Description";"PackSizeNumeric";"BuyersItemIdentification";"CommodityClassification";"Weight";"Tare";PartyIdentification
"ITEM1";"6";"75847589";"856952";"0";"0";"847532"
"ITEM2";"10";"9568475";"348454";"0";"0";"7542125"

推荐答案

选择对象和 Select-Xml 的组合似乎效果很好:

A combination of Select-Object and Select-Xml seems to work pretty well:

$ns = @{
    item="urn:loc.gov:item"
    ns2="urn:loc.gov:box"
    ns3="http://www.example.com/inverter"
    ns4="urn:loc.gov:xyz"
}

$doc = New-Object xml
$doc.Load("test.xml")

$doc.BOX.ChildNodes | Select-Object -Property `
    Description,`
    PackSizeNumeric, `
    @{Name="BuyersItemIdentification_ID"; Expression={$_.BuyersItemIdentification.ID}}, `
    @{Name="CommodityClassification_CommodityCode"; Expression={$_.CommodityClassification.CommodityCode}}, `
    @{Name="Weight"; Expression={Select-Xml -Namespace $ns -Xml $_ -XPath "./ns2:AdditionalItemProperty[item:Name = 'Weight']/item:Value"}}, `
    @{Name="Tare"; Expression={Select-Xml -Namespace $ns -Xml $_ -XPath "./ns2:AdditionalItemProperty[item:Name = 'Tare']/item:Value"}}, `
    @{Name="ManufacturerParty_ID"; Expression={$_.ManufacturerParty.PartyIdentification.ID}} `
| Export-Csv "Stsadm-EnumSites.csv" -NoTypeInformation -Delimiter:";" -Encoding:UTF8

结果( Stsadm-EnumSites.csv )

"Description";"PackSizeNumeric";"BuyersItemIdentification_ID";"CommodityClassification_CommodityCode";"Weight";"Tare";"ManufacturerParty_ID"
"ITEM1";"6";"75847589";"856952";"0";"0";"847532"
"ITEM2";"10";"9568475";"348454";"0";"0";"7542125"
