There was a minor quirk in the original script, as lease dates where being mixed with hostnames in the final output html. As it turns out it was all a matter of what date it was, when I created the script 🙂
Line 21 in the original:
$l = $l -replace '[-]{1}\d{2}[/]\d{2}[/]\d{4}',''
matches dates in the following format: -xx/yy/zzzz but not -x/yy/zzzz or for that matter -xx/y/zzzz.
The correct –replace should have been:
$l = $l -replace '[-]{1}\d{1,2}[/]\d{1,2}[/]\d{4}',''
Thanks you for the comments, which was the final spark to get me to fix it in my production environment 🙂
