Powershell - Get total jobs printed from list of printers - powershell

Question

Trying to get total jobs printed.
It works fine for one printer:
cls
$WebResponse = Invoke-WebRequest "10.240.16.156/server/JOBLOG.htm"
$Total = $WebResponse.AllElements | Select innerText | Select -Index '12'
$Total
Output:
innerText
---------
Total Jobs Printed:737
But I need to get that information from five hundred printers, that IP's I have in .csv file:
"PortName"
"10.240.8.27"
"10.240.9.87"
"10.240.19.81"
...
Tried to import IP from CSV, but it only uses last IP from .csv and cannot build a valid url:
cls
$Printers = Import-Csv -Path C:\path\to\csv\_printers.csv
$Url = "http://$PortName/server/JOBLOG.htm"
$WebResponse = ForEach ($PortName in $Printers) {Invoke-WebRequest $Url}
$Total = $WebResponse.AllElements | Select innerText | Select -Index '12'
ForEach ($PortName in $Printers) {
$Total
}
Output:
Invoke-WebRequest : Cannot bind parameter 'Uri'. Cannot convert value "http://#{PortName=10.240.11.86}/server/JOBLOG.htm" to type "System.Uri". Error: "Invalid URI: The hostname could not
be parsed."
At line:4 char:68
+ ... bResponse = ForEach ($PortName in $Printers) {Invoke-WebRequest $Url}
+ ~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-WebRequest], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
Any help?
Thanks

I'm guessing you're looking for something like this:
Import-Csv -Path C:\path\to\csv\_printers.csv | ForEach-Object {
$Url = "http://{0}/server/JOBLOG.htm" -f $_.PortName
[pscustomobject]#{
URL = $Url
Response = (Invoke-WebRequest $Url).AllElements.InnerText[12]
}
}
The error message is actually showing you the object being converted to a string (#{PortName=10.240.11.86}):
.. Cannot convert value "http://#{PortName=10.240.11.86}/server/JOBLOG.htm" ..
You need to expand the PortName property from your object to get the value (only the IP), hence the use of $_.PortName in my example.
