Question

我正在寻找一个将字符串列表添加到XML对象的解决方案

这来自我需要调用的Web服务的文档：

fileNames：String列表指定多个文件名多个   必须使用fileNames参数，如下所示：

 <xsd1:fileNames>test1.txt</xsd1:fileNames> <xsd1:fileNames>test2.txt</xsd1:fileNames>

不允许添加具有相同名称的第二个属性

$soap.Envelope.Body.sampleobject | Add-Member -MemberType Property -Name fileNamesList -Value $fileNames[0]
#This works fine

$soap.Envelope.Body.sampleobject | Add-Member -MemberType Property -Name fileNamesList -Value $fileNames[1]
#This fails with error message "Add-Member : Cannot add a member with the name "fileNamesList" because a member with that name already exists.  "

如果可能的话，我想避免将SOAP对象作为字符串处理并插入字符串。

有一种优雅的方法可以使用PowerShell来管理它吗？

UPDATE 更多代码

$soap = [xml]@'
<Envelope>
   <Body>
      <sampleObject>
         <Name>MySampleObject</Name>
      </sampleObject>
   </Body>
   </Envelope>
'@

[string[]]$filenames='filea.txt','fileb.txt'

$soap.Envelope.Body.sampleObject | Add-Member -MemberType NoteProperty -Name fileNames -Value $fileNames

$soap.envelope.body.sampleObject | fl   #1
write-host "`r`n" $soap.OuterXml        #2

输出：

＃1：对象包含文件名

fileNames : {filea.txt, fileb.txt}
Name      : MySampleObject

＃2：发送到xml Webservice时缺少文件名

<Envelope><Body><sampleObject><Name>MySampleObject</Name></sampleObject></Body></Envelope>

请勿使用Add-Member修改XML文档。

而是创建一个新节点，并使用sampleObject方法将其附加到AppendChild()：

$soap = [xml]@'
<Envelope>
   <Body>
      <sampleObject>
         <Name>MySampleObject</Name>
      </sampleObject>
   </Body>
   </Envelope>
'@

$filenames='filea.txt','fileb.txt'

foreach($filename in $filenames)
{
    $NewNode = $soap.CreateElement('filenames')
    $NewNode.InnerText = $filename
    [void]$soap.Envelope.Body.sampleObject.AppendChild($NewNode)
}

XML文档现在包含您的filenames个节点：

PS C:\> $soap.OuterXml
<Envelope><Body><sampleObject><Name>MySampleObject</Name><filenames>filea.txt</filenames><filenames>fileb.txt</filenames></sampleObject></Body></Envelope>

Powershell将一个字符串列表添加到对象中
