Powershell foreach loop with multiple if statements - powershell

Question

I have a script snippet that basically gets some unformated xml type output from a command.
Then in a defined filter section I'm transforming that into xml and run a search loop on each node, as from the part below.
What I'm trying to figure out is how I can make a multiple if -and loop, like
if (($CimProperty.VALUE -eq $somevariable) -and ($CimProperty.VALUE -eq $something-else))
The only problem is that since it's a foreach loop it won't take it, as it takes each property at a time and then the 'if statement -and portion' for it, which doesn't work since it's the same xml type property section.
In other words the loop doesn't go through the entire array to identify both conditions from the if statement.
PS code snippet:
filter Import-CimXml
{
$CimXml = [Xml]$_
$CimObj = New-Object -TypeName System.Object
foreach ($CimProperty in $CimXml.SelectNodes(“/INSTANCE/PROPERTY”))
{
if ($CimProperty.VALUE -eq $somevariable)
{
write-host "found it"
}
}
}
I hope the scenario is clear, thanks everyone in advance!

Answer 1

For just two conditions, you can make it fairly straight forward like (the untested);
filter Import-CimXml
{
$foundfirst = $false
$foundsecond = $false
$CimXml = [Xml]$_
$CimObj = New-Object -TypeName System.Object
foreach ($CimProperty in $CimXml.SelectNodes(“/INSTANCE/PROPERTY”))
{
if ($CimProperty.VALUE -eq $somevariable)
{
$foundfirst = $true
}
if ($CimProperty.VALUE -eq $someothervariable)
{
$foundsecond = $true
}
}
if ($foundfirst -and $foundsecond)
{
write-host "found it"
}
}
For more conditions, you may want to use arrays of corresponding matchwords/booleans instead.

Just extend your xpath query to do it all. It's less code and should be more efficient.
filter Import-CimXml
{
$CimXml = [Xml]$_
$CimObj = New-Object -TypeName System.Object
if($CimXml.SelectNodes(“/INSTANCE[PROPERTY='$somevariable' and PROPERTY='$someothervariable']”).Count -gt 0) {
write-host "found it"
}
}
