Question

我想使用Powershell更新XML文件。我想将ServiceManifestVersion更新为某个值。

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

我正在尝试使用以下代码更新值

$buildNo = "001"
$ApplicationManifestPath = "D:\New folder\new1.xml"
$ApplicationManifestString = [string] (Get-Content $ApplicationManifestPath)
$ApplicationManifestXml = [xml]$ApplicationManifestString
$applicationTypeVersionOld = [string]$ApplicationManifestXml.ApplicationManifest.ApplicationTypeVersion
$updatedVersionNumber  =[string] $applicationTypeVersionOld + "-" + $buildNo
$ServiceManifestVersions = $ApplicationManifestXml.ApplicationManifest.ServiceManifestImport.ChildNodes

foreach($ServiceManifestversion in $ServiceManifestVersions)
{
$ApplicationManifestXml.ApplicationManifest.ServiceManifestImport.ServiceManifestRef.ServiceManifestVersion = $updatedVersionNumber
}
$ApplicationManifestXml.Save("D:\New Folder\new 2 .xml")

设置值时，我收到以下错误：

该物业＆＃39; ServiceManifestVersion＆＃39;在这个对象上找不到。验证该属性是否存在且可以设置。

如果我只保留一个节点但是在foreach循环上运行它时出错，那么我能够更新这些值。同时，我能够获取值但不能设置它。任何帮助将不胜感激。

Answer 1

VSTS的人有一些任务。他们是open source。您可以直接在VSTS或TFS中使用任务，也可以在自己的解决方案中使用代码。（它的麻省理工学院获得许可）

Answer 2

将您的foreach更改为：

foreach ($ServiceManifestRef in $ApplicationManifestXml.ApplicationManifest.ServiceManifestImport.ServiceManifestRef)
{
    $ServiceManifestRef.SetAttribute('ServiceManifestVersion', $updatedVersionNumber)
}

物业＆＃39; ServiceManifestVersion＆＃39;在这个对象上找不到。验证该属性是否存在且可以设置
