Sending e-mail using Powershell 3.0

Hello,

I am using powershell to detect which files are recently added to some predefined file locations. See next powershell code:

$time = (Get-Date).AddDays(-30)
$changes =  new-object System.Xml.XmlDocument
$changes.load("C:\test\locations.xml")
      $items = $changes.SelectNodes("//application") | select
      foreach ($item in $items)
        {
                  $location = $item.SelectSingleNode("./location") | % { $_.InnerText }
                  Get-ChildItem $location | `
            Where-Object {$_.LastWriteTime -gt $time}
        }

This files reads the locations defined in the c:\test\locations.xml file, and displays for each of these locations which files are added in the last 30 days.

Now, I want to e-mail this list. The next powershell command works fine when I want to send an e-mail:

Send-MailMessage -To "user@test.nl" -From "noreply@test.nl" -Subject "Test mail"  -Body "This is a test" -SmtpServer "SMTP server"

But now I want to e-mail the filelist. How can I manage to include the result of my first powershell script in the -Body of my second powershell script?

Regards,

Arne
