How about something like this. You can figure out what $value1 and $value2
should look like (could just be your Test-Path calls or maybe the function is
registry aware...).
[bool]function XorValues($value1, $value2, [ref]$outputVal)
{
if ($value1 -xor $value2)
{
If ($value1)
{
$outputVal = $value1
return $true
}
If ($value2)
{
$outputVal = $value2
return $true
}
}
else
{
return $false
}
}

Hey guys,
What is the most elegant way to -xor test two paths and keep the one that
exists?
I have a bunch of cases where I check for the existence of two reg keys (both
can not co-exist) and then set a variable based on either one.
If ((Test-Path "hklm:\..." ) -xor (Test-Path "hklm:\..." )) {
$var = value1 or value2
} Else {
<must exit the script>
}
is the logic I need, but then I need additional code to set a single variable
to value1 or value2.
Not a big deal once, but I have several and I was just hoping for a slick way
to accomplish setting $var to either value based on which side tests true w/o
another if block.
Thanks,
jlc
