我创建了一个简短的PowerShell脚本，用于从Web服务中提取一些XML。这似乎有效。我运行了一个tcpdump，可以看到返回的正确XML。如果我运行get-member，我会看到所有正确的参数。但是，当我尝试输出任何这些参数时，我什么也看不见。没有错误，它似乎只输出任何东西。
Function Get-AssetByMacAddress {
Param(
[Parameter(Mandatory=$true)]
[string]$mac
)
$username = "abc"
$password = ConvertTo-SecureString 'xyz' -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential($username, $password)
$uri = "http://mywebservice.com/assetservice.asmx?WSDL"
# print password (testing)
$cred.GetNetworkCredential().password
# Create web service
$phatWebService = New-WebServiceProxy -Uri $uri -Credential $cred -Namespace "PhatWebService"
# Call method
$phatWebService.GetAssetByMacAddress($mac)
}
$xml = Get-AssetByMacAddress -mac "90:b1:1c:61:8e:41"
$xml | get-member
Write-Host "**************************"
Write-Host $xml.CurrencyCodeBook

出于某种原因，当我尝试查看属性＆＃34; CurrencyCodeBook＆＃34;时，它再次向我展示了所有成员属性。
一些Google搜索建议我需要将Web服务方法定义为[xml]
E.g。
[xml]$phatWebService.GetAssetByMacAddress($mac)
...但这只是给我一个错误＆＃34;根级别的数据无效＆＃34;
答案 0 :(得分：0)
尝试这样：
$wsdl = "http://mywebservice.com/assetservice.asmx?WSDL"
$proxy = New-WebServiceProxy -Uri $wsdl -Namespace WebServiceProx
$sample = $proxy.GetAssetByMacAddress($mac)
[xml]$xmlfile = $sample
现在获取值
$fullName = $xmlfile.AssetInfo.FullName
$hostName = $xmlfile.AssetInfo.HostName
$httpPort = $xmlfile.AssetInfo.HttpPort
OR
$fullName = $xmlfile.FullName
$hostName = $xmlfile.HostName
$httpPort = $xmlfile.HttpPort
编辑：
尝试检查您的xml文件。你能在这里发布xml文件吗？
