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$.

Update: Oops - I had intended to respond to the original post - but got OGB's post instead. Sorry.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
