Inno Setup: How to update AppVersion [Setup] value from Config.xml file

问题

I want to update AppVersion value in [Setup] section at compile time from config.xml file by parsing Version tag.

Config.xml file has below configuration:

<?xml version="1.0" encoding="utf-8"?>
<Configuration> 
  <Version>1.0.1</Version>
</Configuration>

My application is using config.xml file for application version. I also want to use the same version in Inno Setup installer version.

I am new in Inno Setup script development. It would be very helpful if someone provide me right approach.

You can use a simple PowerShell code like:

$version = ([xml](Get-Content 'config.xml')).Configuration.Version
Set-Content -Path 'version.txt' -Value $version

And run it using Inno Setup preprocessor:

#define RetrieveVersion(str FileName) \
  Local[0] = AddBackslash(GetEnv("TEMP")) + "version.txt", \
  Local[1] = \
    "-ExecutionPolicy Bypass -Command """ + \
    "$version = ([xml](Get-Content '" + FileName + "')).Configuration.Version; " + \
    "Set-Content -Path '" + Local[0] + "' -Value $version;" + \
    """", \
  Exec("powershell.exe", Local[1], SourcePath, , SW_HIDE), \
  Local[2] = FileOpen(Local[0]), \
  Local[3] = FileRead(Local[2]), \
  FileClose(Local[2]), \
  DeleteFileNow(Local[0]), \
  Local[3]

[Setup]
AppVersion={#RetrieveVersion("C:\path\config.xml")}

Though I assume that the application compiler actually uses the config.xml for the application executable version. If that's the case, you can retrieve the version from the .exe more easily.
