I'm using a function from dmitrysotnikov.wordpress.com to measure the latest datetime value (it works). I'm just having trouble telling it to select the body of the message with the newest date.

function Measure-Latest {
    begin { $latest = $null }
    process {
            if (($_ -ne $null) -and (($latest -eq $null) -or ($_ -gt 
$latest))) {
                $latest = $_ 
            }
    }
    end { $latest }
}

$webclient = new-object System.Net.WebClient

$webclient.Credentials = new-object System.Net.NetworkCredential 
("[email protected]", "PASSWORD")

[xml]$xml= 
$webclient.DownloadString("https://mail.google.com/mail/feed/atom")

$latestmail = $xml.feed.entry.issued | Measure-Latest

Answer 1

You're almost there! The final step is to specify you want the e-mail which has the $latestmail time-stamp as the issued property, and that you want the summary property of that e-mail:

($xml.feed.entry | Where-Object {$_.issued -eq $latestmail}).summary
