构建自定义XML文件

Question

我需要一些帮助，以使用Powershell构建XML文件。我从来没有这样做过。

刚开始的时候我觉得很幸运，试过了“Export-Clixml”，但是它不会像我想要的那样产生输出。我需要干净的XML。

我有一个现有的XML的文件，它看起来像这样：

<?xml version="1.0" encoding="utf-8"?> 
<DeploymentScript> 
    <Settings> 
    ... 
    </Settings> 
</DeploymentScript> 

我宣读了XML的设置，并做一些东西在PowerShell中。我创建一个对象，它看起来像这样：

TaskSequenceNumber TaskSequenceName 
------------------ ---------------- 
0 01_Base 
1 02_XA 

我要救这个对象在我的XML文件。 （追加） 的XML文件应该最终是这样的：

<?xml version="1.0" encoding="utf-8"?> 
<DeploymentScript> 
    <Settings> 
    ... 
    </Settings> 
    <Deploy> 
    <SequenceData> 
     <TaskSequenceNumber>1</TaskSequenceNumber> 
     <TaskSequenceName>01_Base</TaskSequenceName> 
    </SequenceData> 
    <SequenceData> 
     <TaskSequenceNumber>2</TaskSequenceNumber> 
     <TaskSequenceName>02_XA</TaskSequenceName> 
    </SequenceData> 
    </Deploy> 
</DeploymentScript> 

我已经尝试了一些.NET XML的方法，但我没有得到一个结果。 有人会举例说明如何做到这一点？

。

编辑： 感谢“Frode F.”！这里的最新代码：

$xml = [xml]@" 
<?xml version="1.0" encoding="utf-8"?> 
<DeploymentScript> 
    <Settings> 
    ... 
    </Settings> 
</DeploymentScript> 
"@ 

#$xml = [xml](Get-Content -Path "$env:USERPROFILE\Desktop\Deploy-Settings.xml") 
$TaskSequences = [pscustomobject]@{TaskSequenceNumber=0;TaskSequenceName="01_Base"},[pscustomobject]@{TaskSequenceNumber=1;TaskSequenceName="02_XA"} 

#Add Deploy-node 
$DeployNode = $xml.CreateElement("Deploy") 
$xml.DeploymentScript.AppendChild($DeployNode) > $null 

foreach ($element in $TaskSequences) { 

    $SeqDataNode = ([xml]@" 
<SequenceData> 
    <TaskSequenceNumber>$($element.TaskSequenceNumber + 1)</TaskSequenceNumber> 
    <TaskSequenceName>$($element.TaskSequenceName)</TaskSequenceName> 
</SequenceData> 
"@).FirstChild 

    #Add to Deploy-node 
    $DeployNode.AppendChild($xml.ImportNode($SeqDataNode,$true)) > $null 

} 

$xml.Save("$env:USERPROFILE\Desktop\Test.xml")

你可以通过在.NET中使用XML类尝试这样的事：

#SampleInput 
$xml = [xml]@" 
<?xml version="1.0" encoding="utf-8"?> 
<Settings> 
    ... 
</Settings> 
"@ 

$TaskSequences = [pscustomobject]@{TaskSequenceNumber=0;TaskSequenceName="01_Base"},[pscustomobject]@{TaskSequenceNumber=1;TaskSequenceName="02_XA"} 

#$xml = [xml](Get-Content -Path InputFile.xml) 
#$TaskSequences = Get-RealDataFromSomeWhere 

#Create new xml and remove root node 
$newxml = $xml.Clone() 
$newxml.RemoveChild($newxml.SelectSingleNode("/Settings")) > $null 

#Add new DeploymentScript root-node with copy of Settings 
$DeploymentScriptNode = $newxml.CreateElement("DeploymentScript") 
$DeploymentScriptNode.AppendChild($newxml.ImportNode($xml.SelectSingleNode("/Settings"),$true)) > $null 
$newxml.AppendChild($DeploymentScriptNode) > $null 

#Add Deploy-node 
$DeployNode = $newxml.CreateElement("Deploy") 
$DeploymentScriptNode.AppendChild($DeployNode) > $null 

foreach ($ts in $TaskSequences) { 
    #Create SequenceData-element per TS 
    $SeqDataNode = $newxml.CreateElement("SequenceData") 

    $SeqDataNode.AppendChild($newxml.CreateElement("TaskSequenceNumber")) > $null 
    $SeqDataNode.AppendChild($newxml.CreateElement("TaskSequenceName")) > $null 

    $SeqDataNode.TaskSequenceNumber = "$($ts.TaskSequenceNumber + 1)" 
    $SeqDataNode.TaskSequenceName = $ts.TaskSequenceName 

    #Add to Deploy-node 
    $DeployNode.AppendChild($SeqDataNode) > $null 
} 

$newxml.Save("$env:USERPROFILE\Desktop\Test.xml") 

还是凌乱，但较短，字符串的方法：

#SampleInput 
$xml = [xml]@" 
<?xml version="1.0" encoding="utf-8"?> 
<Settings> 
    ... 
</Settings> 
"@ 

$TaskSequences = [pscustomobject]@{TaskSequenceNumber=0;TaskSequenceName="01_Base"},[pscustomobject]@{TaskSequenceNumber=1;TaskSequenceName="02_XA"} 

#$xml = [xml](Get-Content -Path InputFile.xml) 
#$TaskSequences = Get-RealDataFromSomeWhere 

#Create new xml and remove root node 
$newxml = [xml]@" 
$($xml.FirstChild | ? { $_.NodeType -eq 'XmlDeclaration' } | % { $_.OuterXml }) 
<DeploymentScript> 
    $($xml.SelectSingleNode("/Settings").OuterXml) 
    <Deploy> 
    $($TaskSequences | % { 
    "<SequenceData> 
     <TaskSequenceNumber>$($_.TaskSequenceNumber + 1)</TaskSequenceNumber> 
     <TaskSequenceName>$($_.TaskSequenceName)</TaskSequenceName> 
    </SequenceData>" }) 
    </Deploy> 
</DeploymentScript> 
"@ 


$newxml.Save("$env:USERPROFILE\Desktop\Test.xml") 

Test.xml：

<?xml version="1.0" encoding="utf-8"?> 
<DeploymentScript> 
    <Settings> 
    ... 
</Settings> 
    <Deploy> 
    <SequenceData> 
     <TaskSequenceNumber>1</TaskSequenceNumber> 
     <TaskSequenceName>01_Base</TaskSequenceName> 
    </SequenceData> 
    <SequenceData> 
     <TaskSequenceNumber>2</TaskSequenceNumber> 
     <TaskSequenceName>02_XA</TaskSequenceName> 
    </SequenceData> 
    </Deploy> 
</DeploymentScript>
