पावरशेल का उपयोग करके मैं XML को कैसे संपादित करूं?

Question

मैं पावरहेल में कुछ एक्सएमएल संपादित करने की कोशिश कर रहा हूं। यहाँ मैं क्या कर रहा है:

$path = 'C:\Projects\NuGetTestPackage\NuGetTestPackage' 
$projName = 'NuGetTestPackage1.csproj' 
cd $path 
$file = gi $projName 
$pattern = 'TextTemplatingFileGenerator' 
$xml = [xml](gc $file) 
$node = [xml] $xml.Project.ItemGroup.None.Generator | 
    Where { $_.Project.ItemGroup.None.Generator -eq $pattern } | 
    Foreach {$_.Project.ItemGroup.None.Generator = ''} 
$xml.Save($file.Fullname) 

यहाँ एक्सएमएल है:

विचार जेनरेटर नोड के मूल्य को अनुमति देना। मुझे यह कोड काम करने के लिए प्रतीत नहीं होता है। क्या मैं एक्सएमएल गुणों को गलत तरीके से एक्सेस कर रहा हूं? ऐसा लगता है कि मुझे प्रत्येक के लिए एक मूल्य वापस मिलता है, लेकिन मुझे इसे सही तरीके से एक्सेस करने में समस्या हो रही है।

ठीक है, धन्यवाद @ केथ हिल।

$path = 'C:\Projects\NuGetTestPackage\NuGetTestPackage' 
$ns = @{msb = 'http://schemas.microsoft.com/developer/msbuild/2003'} 
cd $path 
$results = 0 
$projName = 'NuGetTestPackage1.csproj' 
$file = gi $projName 
$xml = [xml](gc $projName) 
$xml | Select-Xml "//msb:Generator" -Namespace $ns | 
     Foreach { 
      $_.Node.set_InnerText('') 
      $results = 1 
     } 
if($results -eq 1){ 
    $xml.Save($file.FullName) 
} 

Answer 1

इसका कारण यह है कि आप क्या हो रहा है एक से अधिक "आइटम समूह" तत्व और एक से अधिक "कोई नहीं" तत्व है। उस समय, आइटम समूह एक संग्रह है और इसमें "कोई नहीं" संपत्ति नहीं है। आप XPath IMO का उपयोग करना बेहतर होगा .:

$ns = @{msb = 'http://schemas.microsoft.com/developer/msbuild/2003'} 
$pattern = 'TextTemplatingFileGenerator' 
$xml = [xml](gc C:\temp\test.csproj) 
$xml | Select-Xml "//msb:Generator[text() = $pattern]" -Namespace $ns | 
     Foreach {$_.Node.set_InnerText('')} 
$xml.Save('C:\temp\test.csproj') 

Answer 2

मैं वास्तव में आपकी समस्या

$file = get-item "c:\Yourfile.xml" 

$xml = [xml](get-content $file) 

$xml.Project.ItemGroup.None.Generator = "" 

$xml.Save("c:\YourModifiedFile.xml")

संपादित समझ में नहीं आता:: यहाँ जवाब पहली बार दिया फ़ाइल था:

<?xml version="1.0" encoding="utf-8"?>
