如何同时节约使用PowerShell

Question

以下XML字符串去除特殊字符是PowerShell的代码，我使用从web.config文件中删除父节点：

$c = "C:\test\web.config" 
    $xml = (Get-Content $c) 
    $ConnectionString = $xml.configuration.appSettings.add | Where-Object {$_.Key -eq 'ConnectionString'} 
    $xml.configuration.RemoveChild($ConnectionString.ParentNode) 
    $xml.save($c) 

After removing <appSettings> tag from web.config file. Some special Characters like &#xA; are adding to web.config file as below: 

<?xml version="1.0"?> 
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> 
    <configSections> 
    <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, &#xA;  System.Web.Extensions, Version=3.5.0.0, Culture=neutral, &#xA;  PublicKeyToken=31bf3856ad364e35"> 
    </configSections> 
</configuration> 

请让我知道如何保存XML文件无特殊字符，如

刚把这个问题，我过滤所有非ASCII-256字符与此正则表达式

$myText = # your text here 
$cleanText = ($myText -replace"[^\x00-\xFF]",""); 

你确定这应删除字符？您也可以尝试更改编码，像这样

$myText | Out-File -FilePath "yourPath" -Encoding utf8 

我已经使用
