遍历xml元素 [英] Loop through xml elements

问题描述

我有以下内容:

$aMyArray = $null


[xml]$userfile = Get-Content C:\AppSense\Scripts\AmPolicyConversion\AM_dev.xml

$i = 0
FOREACH ($j in $userfile.ChildNodes){

    FOREACH($k in $j.DocumentElement) {

    }

    $i = $i + 1
}

我试图弄清楚如何在powershell中循环遍历每个元素.

I am trying to figure out how to loop through each element within powershell.

然后检查元素上SID的属性.

Then check for an attribute of SID on the element.

如果存在，则获取属性值并将该值放入对象中，对于同一元素，获取第二个属性DISPLAYNAME并放入同一对象中.我们将创建一个对象数组.

If exists get attribute value and put that value into an object and for the same element grab second attribute DISPLAYNAME and place into same object. We will create an array of objects.

我知道我还有路要走，但希望您能提供帮助.

I know I am way off but hope you can help.

推荐答案

使用XPATH来查找具有SID属性的所有节点，如下所示:

Use XPATH instead to find all nodes with a SID attribute like so:

$objs = @()
$nodes = $userfile.SelectNodes("//*[@SID]")
foreach ($node in $nodes) {
    $sid = $node.attributes['SID'].value
    $dispName = $node.attributes['DISPLAYNAME'].value
    $obj = new-object psobject -prop @{SID=$sid;DISPNAME=$dispName}
    $objs += $obj
}
$objs

这是一个输出示例:

$xml = [xml]@"
<doc>
  <foo SID='foosid' DISPLAYNAME="foodisp">
    <bar SID='barsid' DISPLAYNAME="bardisp"/>
    <baz>
      <blech SID='blechsid' DISPLAYNAME="blechdisp"/>
    </baz>
  </foo>
</doc>
"@

$objs = @()
$nodes = $xml.SelectNodes("//*[@SID]")
foreach ($node in $nodes) {
    $sid = $node.attributes['SID'].value
    $dispName = $node.attributes['DISPLAYNAME'].value
    $obj = new-object psobject -prop @{SID=$sid;DISPNAME=$dispName}
    $objs += $obj
}
$objs

输出:

SID                       DISPNAME                
---                       --------                
foosid                    foodisp                 
barsid                    bardisp                 
blechsid                  blechdisp
