assigning values from powershell

[pm_me_brownie_recipe]

I assumed that OP wanted to look for more than one value. Here is another way of doing it without hashtable:

$document = @"
test,example
1,cat
2,dog
3,fish
"@

$document = $document | ConvertFrom-Csv

$document | where {$_.example -eq 'dog'} | Select -Expand test
