PowerShell的XML属性命名空间

Question

我有以下存根XML文件

<ResourceDictionary x:Uid="CultureResources" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:system="clr-namespace:System;assembly=mscorlib" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 

<system:String x:Uid="system::.CultureName" x:Key=".CultureName">de-DE</system:String> 

</ResourceDictionary> 

我绑自动生成它在它目前正与下面的测试代码

[xml]$xmlfile = Get-Content "c:\test.xml" 

[System.Xml.XmlNamespaceManager] $nsm = new-object System.Xml.XmlNamespaceManager $xmlfile.NameTable 
$nsm.AddNamespace("x", "http://schemas.microsoft.com/winfx/2006/xaml") 
$nsm.AddNamespace("system", "clr-namespace:System;assembly=mscorlib") 

$nn = $xmlfile.CreateElement("system:String", $nsm) 
$nn.set_InnerText("de-DE") 
$nn.SetAttribute("Uid","system:.CultureName") 
$nn.SetAttribute("Key",".CultureName") 
$xmlfile.ResourceDictionary.AppendChild($nn) 

但显示相同的方式输出我得到的是

<ResourceDictionary x:Uid="CultureResources" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:system="clr-namespace:System;assembly=mscorlib" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 

<system:String x:Uid="system::.CultureName" x:Key=".CultureName">de-DE</system:String> 
<system:String Uid="system:.CultureName" Key=".CultureName" xmlns:system=" xmlns xml x system">de-DE</system:String> 
</ResourceDictionary> 

我如何：

A）摆脱了命名空间文本

xmlns:system=" xmlns xml x system" 

B）的前缀属性我用 “X：”

任何帮助，将不胜感激。

问候，

您需要使用另一个超负荷createelement()和setattribute()指定的namespaceURI。获得uri的一个简单方法是在需要时从$nms获得uri。试试这个：

$xml = [xml]@" 
<ResourceDictionary x:Uid="CultureResources" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:system="clr-namespace:System;assembly=mscorlib" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 

<system:String x:Uid="system::.CultureName" x:Key=".CultureName">de-DE</system:String> 

</ResourceDictionary> 
"@ 

[System.Xml.XmlNamespaceManager] $nsm = new-object System.Xml.XmlNamespaceManager $xml.NameTable 
$nsm.AddNamespace("x", "http://schemas.microsoft.com/winfx/2006/xaml") 
$nsm.AddNamespace("system", "clr-namespace:System;assembly=mscorlib") 


#$nn = $xml.CreateElement("system", "String", $nsm.LookupNamespace("system")) this works too: prefix, name, NSuri 
$nn = $xml.CreateElement("system:String", $nsm.LookupNamespace("system")) 
$nn.set_InnerText("de-DE") 
$nn.SetAttribute("Uid", $nsm.LookupNamespace("x"), "system::.CultureName") 
$nn.SetAttribute("Key", $nsm.LookupNamespace("x"), ".CultureName") 
$xml.ResourceDictionary.AppendChild($nn) 
$xml.Save("C:\users\graimer\Desktop\test.xml") 

的test.xml

<ResourceDictionary x:Uid="CultureResources" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:system="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 
    <system:String x:Uid="system::.CultureName" x:Key=".CultureName">de-DE</system:String> 
    <system:String x:Uid="system::.CultureName" x:Key=".CultureName">de-DE</system:String> 
</ResourceDictionary>
