• Get current ps1 file's parent path

$x = Split-Path -Parent $MyInvocation.MyCommand.Definition

•  Create a folder if it does not exist.

$myNewFolder = $x +"myTestFolder\"

if(!(Test-Path $myNewFolder))

{

new-item -path $x -name myTestFolder -type directory

}

• Open a XML file , and get what we want.

[String]$xmlDocPath = "F:/TestData/TestXml.xml"

[String]$nodeName = "Property"



$xmlDoc = New-Object "System.Xml.XmlDocument"

$xmlDoc.Load($xmlDocPath)

$nodelist = $xmlDoc.GetElementsByTagName($nodeName);

foreach($node in $nodelist)

{ 

　　# Use Attributes will throw error.

　　#$namestr = $node.Attributes[0].InnerXml

　　#Write-Host "$namestr" 

　　$namestr = $node.GetAttribute("Value")

　　Write-Host "$namestr" 

　　$childnodes= $node.ChildNodes;

　　foreach($childnode in $childnodes )

　　{

　　　　$textstr = $childnode.InnerXml.ToString()

　　　　Write-Host "$textstr"

　　}

}

foreach ($i in $colItems)

    {

        $subFolderItems = (Get-ChildItem $i.FullName -recurse | Measure-Object -property length -sum)
