It seems OK but I don't know why it doesn't have any output. Any response would be appreciated.
Read this if you want to cut your development time in half!
Your code is not strict/warnings compliant, they would warn you about typos, undeclared variables ... like $taxId in sub getDistance and $taxId1 in sub getParent
I guess that you're using assignment while ($taxId = $taxId1){ instead of numeric comparison operator ==
You initialize an array with an empty string my @parent_list = "";, this doesn't seem intentional, the = "" portion isn't required for empty array
An array in scalar context returns the number of elements, so $id = getParent ($taxId); seems fishy.
Do you want the number of elements in @parent_list? First element? Last element? Something else?
I would fix up your code (its short enough) , but its not obvious from the code what sub getParent should return , this means the sub needs documentation, even for perlmonks :) input, output... How do I post a question effectively?
I reccoment you read Tutorials: Context tutorial, Variable Scoping in Perl: the basics, Coping with Scoping
