读取.xml文件时无限循环



我制作了一个PowerShell脚本来读取和写入信息/设置到.xml文件。

Param(
    [string]$mode,
    [string]$set,
    [string]$xml
)
function readSettings([string]$xmlfile, [string]$setting)
{
    $s = readSettings $xmlfile
    $v = $s[$setting]
    Write-Host $v
}
function exportSettings([string]$xmlfile)
{
    $xmlDoc = New-Object XML
    $xmlDoc.Load($xmlfile)
    $settings = @{}
    $xmlDoc.settings.ChildNodes | %{$settings[$_.name] = $_.firstChild.Value}
    return $settings
}
function importSettings([hashtable]$ht,[string]$xmlFile){
    $xmlDoc = New-Object XML
    $xmlDoc.Load($xmlFile)
    foreach ($key in $ht.keys){
        $settingNode = $xmlDoc.SelectSingleNode("/settings/setting[@name='$key']")
        if ($settingNode){
            $settingNode.firstChild.Value = $ht[$key]
        }else{
            $newNode = $xmlDoc.settings.setting[0].Clone()
            $newNode.name = $key
            $newNode.firstChild.Value = $ht[$key]
            $xmlDoc.settings.appendChild($newNode)
        }
    }
    $xmlDoc.Save($xmlFile)
}
if($mode -eq "read")
{
    readSettings($xml, $set)
}
if ($mode -eq "write")
{
}

(也在GitHub上。

每当我读取.xml文件时,它都会生成一个无限循环,RAM 消耗高达 2GB。

我以为

$xmlDoc.settings.ChildNodes | %{$settings[$_.name] = $_.firstChild.Value}

可能是原因,但我不知道如何解决。写入 xml 文件工作得很好。谁能帮忙?

我认为readSettings函数无需测试即可调用自己,我认为这足以循环。

function readSettings([string]$xmlfile, [string]$setting)
{
    $s = readSettings $xmlfile
    $v = $s[$setting]
    Write-Host $v
}

我很迟钝...我调用了错误的函数...

应该是 $s = exportSettings $xmlfile

对不起,伙计们浪费了你的时间:)

少一个问题...

谢谢你们!

如果您需要:

function xml_readSettings([string]$xmlfile, [string]$setting)
{
    $xmlDoc = New-Object XML
    $xmlDoc.Load($xmlfile)
    $settings = @{}
    $xmlDoc.settings.ChildNodes | %{$settings[$_.name] = $_.firstChild.Value}
    return $settings[$setting]
}
function xml_exportHashtable([string]$xmlfile)
{
    $xmlDoc = New-Object XML
    $xmlDoc.Load($xmlfile)
    $settings = @{}
    $xmlDoc.settings.ChildNodes | %{$settings[$_.name] = $_.firstChild.Value}
    return $settings
}
function xml_writeSettings([hashtable]$ht, [string]$xmlfile)
{
    $xmlDoc = New-Object XML
    $xmlDoc.Load($xmlFile)
    foreach ($key in $ht.keys){
        $settingNode = $xmlDoc.SelectSingleNode("/settings/setting[@name='$key']")
        if ($settingNode){
            $settingNode.firstChild.Value = $ht[$key]
        }else{
            $newNode = $xmlDoc.settings.setting[0].Clone()
            $newNode.name = $key
            $newNode.firstChild.Value = $ht[$key]
            $xmlDoc.settings.appendChild($newNode)
        }
    }
    $xmlDoc.Save($xmlFile)
}

它现在的工作:)
