I have an internal web app that provides connection statistics. I am trying to use PS to collect those statistics, which are in .conent. The .content property has a lot of other values I am trying to filter out and I haven't been very successful.
My Command:
invoke-webrequest -URI http://<my internal web site> | Select-Object -ExpandProperty Content
Returned Results:

They only line I care about is "Current Active Sessions: 6" and really all I care about is the numerical value which I will use in a test later in the script.
How can I just grab the one value I need?
$iwr=invoke-webrequest -URI http://<my internal web site> |
Select-Object -ExpandProperty Content
$cas=$iwr -split [System.Environment]::NewLine |
Select-String -Pattern "Current Active Sessions:\s*(.*)"
$cas.Matches[0].Groups[1].Value
Above code snippet should return 6. Tested using the following (constant) value of $iwr instead of invoke-webrequest:
$iwr=@'
