This one-line does the job (With your current sample data):

perl -000 -ne '($l,$d)=m/Location:\s+(\S+).+BuildDate:\s+(\d.+\d)/s; (
+$lm,$ld)=($l,$d) if $d gt $ld and m/Approved/s}{print qq|$lm\n|' YOUR
+-FILE-NAME.txt

Note1 - the Date compare logic is very weak - it simply does a textual compare.
Note2 - "Approved" verification is very weak.
This is a working sample - you can use it to build a more robust program.
Change single-quotes to double, if you use Window$.
