请求编写PowerShell脚本为指定VM的XML配置文件插入配置项

Got it, here's a PowerShell script that'll handle inserting those two log configuration keys exactly where you need them — between <add key="LogFilePath"/> and <add key="FtpEnabled"/> under your Run1, Run2, and any other Run* nodes in your XML config:

# Replace this with the actual path to your XML configuration file
$xmlPath = "C:\Path\To\Your\ConfigFile.xml"

# Load the XML file
$xml = [xml](Get-Content $xmlPath)

# Target all nodes starting with "Run" (matches Run1, Run2, etc.)
$runNodes = $xml.SelectNodes("//*[starts-with(local-name(), 'Run')]")

foreach ($runNode in $runNodes) {
    # Find the LogFilePath node within the current Run node
    $logFilePathNode = $runNode.SelectSingleNode("./add[@key='LogFilePath']")
    if ($logFilePathNode -eq $null) {
        Write-Warning "Skipping $($runNode.Name) - LogFilePath node not found"
        continue
    }

    # Find the FtpEnabled node to confirm insertion position (optional but safe)
    $ftpEnabledNode = $runNode.SelectSingleNode("./add[@key='FtpEnabled']")
    if ($ftpEnabledNode -eq $null) {
        Write-Warning "Skipping $($runNode.Name) - FtpEnabled node not found"
        continue
    }

    # Create the LogFileSizeLimit node
    $sizeLimitNode = $xml.CreateElement("add")
    $sizeLimitNode.SetAttribute("key", "LogFileSizeLimit")
    $sizeLimitNode.SetAttribute("value", "40")

    # Create the LogFileArchiveCount node
    $archiveCountNode = $xml.CreateElement("add")
    $archiveCountNode.SetAttribute("key", "LogFileArchiveCount")
    $archiveCountNode.SetAttribute("value", "2")

    # Insert both nodes RIGHT AFTER LogFilePath (so they land between LogFilePath and FtpEnabled)
    $runNode.InsertAfter($sizeLimitNode, $logFilePathNode)
    $runNode.InsertAfter($archiveCountNode, $sizeLimitNode)
}

# Save the modified XML back to the file
try {
    $xml.Save($xmlPath)
    Write-Host "Successfully updated XML configuration file at $xmlPath" -ForegroundColor Green
} catch {
    Write-Error "Failed to save XML file: $_"
}

Key Notes & Safety Tips: #

• Backup First: Always make a copy of your original XML file before running this script — just in case!
• Path Replacement: Don't forget to replace the $xmlPath value with your actual config file path.
• Namespace Handling: If your XML uses a namespace, you'll need to adjust the XPath queries to include it. For example, if your root has xmlns="http://example.com/config", you'll need to define a namespace manager and use it in SelectNodes/SelectSingleNode.
• Validation: After running the script, open your XML file to verify the new nodes are in the correct position between LogFilePath and FtpEnabled.
