So the first piece of code could be cut down to

There's still room for improvement, like
adding an //x modifier, particularly if you are "not very good"
at grokking regexes:
if ( $details[$i] =~ /\bworkstation
\s
name:
\s
(
[0-9A-Za-z_-]+
)
/ix
)
e.g. removing A-Z from
the character class, as you are giving the /i modifier anyway,
so both upper and lowercase characters will be matched.
and removing the backslash. Hyphen is not meta in a character
class if it is first or last in the class.
