在每次部署后使用PowerShell自动增加应用程序.config的版本

问题描述

我是PowerShell的新手，我想在每次部署和之后更改XML文件中的版本。我指的是Unable to update a value in msbuild proj file using powershell。以下是XML内容：

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


      <add key="ShowAppConf" value="true"/>
      <add key="site.IsCsrfCheck" value="false" />
      <add key="EnableDeviceFileAuthentication" value="false" />
      <add key="EnableFileAuthentication" value="false" />
      <add key="AppVersion" value="v0.1.7.21.31.144402" />


    </site>
</configuration>  

我正在尝试通过以下方式增加AppVersion修订版的价值：

$Test1QAMSBuildFile = 'D:	estapplication.config.xml'
[xml]$Test1QABuildVersion = Get-Content $Test1QAMSBuildFile
$node = $Test1QABuildVersion.SelectSingleNode("/configuration/site/key/AppVersion")
$PropertyVersion= $node.InnerText
$UpdateVersion= $PropertyVersion.split(".")
$UpdateVersion[4] = (($UpdateVersion[4] -as [int]) + 1).ToString()
$newVersion = $UpdateVersion -join '.'
$node.InnerText = $newVersion
$Test1QABuildVersion.Save($Test1QAMSBuildFile)

运行此脚本后，PowerShell ISE引发错误：

You cannot call a method on a null-valued expression.
At line:5 char:1
+ $UpdateVersion= $PropertyVersion.split(".")
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

Cannot index into a null array.
At line:6 char:1
+ $UpdateVersion[4] = (($UpdateVersion[3] -as [int]) + 1).ToString()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : NullArray

The property 'InnerText' cannot be found on this object. Verify that the property exists and can be set.

+ $node.InnerText = $newVersion
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyNotFound

如何使用PowerShell自动增加版本。

推荐答案

AppVersion是<add>节点的属性值，不是节点的名称。此外，您还希望提取节点的value属性的值，而不是节点的innerText属性的值。

       ,- node name
      /
     /   ,- attribute name
    /   /
   /   /       ,- attribute value
  /   /       /
<add key="AppVersion" value="v0.1.7.21.31.144402">
  something
</add>   
          `- inner text

在XPath表达式中选择如下属性：

//node[@attribute='value']

更改这两行：

$node = $Test1QABuildVersion.SelectSingleNode("/configuration/site/key/AppVersion")
$PropertyVersion= $node.InnerText

进入：

$node = $Test1QABuildVersion.SelectSingleNode("/configuration/site/add[@key='AppVersion']")
$PropertyVersion= $node.value

并按如下方式更新版本号：

$node.value = $newVersion
