You may have a situation where you need to dynamically change or update a file within the Windows executor. Usually, this would be to update a config file.
XML File Change Example
If the file you need to change is written in XML, the following is an example of how such an update would be made:
jobs: build: machine: image: windows-server-2019-vs2019:stable shell: powershell.exe environment: NEW_URL: "https://newurl.org" steps: - checkout - run: name: Update config file command: | Write-Host("Displaying Original Config"); type C:\Users\circleci\project\test.config [xml]$XmlDocument = Get-Content -Path C:\Users\circleci\project\test.config $url = $XmlDocument.SelectSingleNode("configuration/Test/add[@value='https://something.com/']"); $url.value = "$env:NEW_URL"; $XmlDocument.Save("C:\Users\circleci\project\test.config") Write-Host("Displaying Updated Config"); type C:\Users\circleci\project\test.config
The above run command is adjusting the URL present in the following
Write-Host commands are present just to verify the change and can be removed as needed.
