マルチレベルJSON配列を解析する方法は？

Question

ここに私のData.jsonがあります。それはマルチレベルの配列を持っています。私はすべての配列要素を取得する必要があります。

{ 
    "host": "http://localhost:5000", 
    "dlls": [ 
    { 
     "files": [ 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     } 
     ] 
    }, 
    { 
     "json": [ 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json" 
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     } 
     ] 
    } 
    ] 
} 

私の現在のPSスクリプトでは、私は一度繰り返すことができます：

$json = $null; 
$jsonparsed = $null; 
$validJson = $false; 
try { 
    $json = Get-Content -Raw $file; 
    $jsonparsed = ConvertFrom-Json $json -ErrorAction Stop; 
    $validJson = $true; 
} catch { 
    $validJson = $false; 
} 

if ($validJson) { 
    Write-Host "Provided text has been correctly parsed to JSON"; 
    Write-Host $jsonparsed; 
} else { 
    Write-Host "Provided text is not a valid JSON string" -ForegroundColor "Red"; 
    return; 
} 

を私はすべてのJSONの配列要素を解析する必要があります。各「パス」と「ストア」の値を取得します。 PowerShellバージョン5でどうすればいいですか？私はサードパーティのアセンブリを読み込んで解決策を見つけました。しかし、私は外部のアセンブリを使用することはできません。それは外部のアセンブリなしで解析可能ですか？

あなたはPowerShellの（V5）ウィンドウにこれを貼り付ける場合：

$jsonparsed = convertFrom-Json @' 
{ 
    "host": "http://localhost:5000", 
    "dlls": [ 
    { 
     "files": [ 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     }, 
     { 
      "path": ".\\Xml.dll", 
      "store": ".\\DX\\OpenXml.dll" 
     } 
     ] 
    }, 
    { 
     "json": [ 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json" 
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     }, 
     { 
      "path": ".\\index.json", 
      "store": ".\\DX\\index.json"   
     } 
     ] 
    } 
    ] 
} 
'@ 

Write-Host $jsonparsed.host 
ForEach ($dll in $jsonparsed.dlls) { 
    ForEach ($file in $dll.files) { 
     Write-Host $file.path 
     Write-Host $file.store 
    } 
    ForEach ($json in $dll.json) { 
     Write-Host $json.path 
     Write-Host $json.store 
    } 
} 

あなたはこの取得する必要があります。
