Fetch respective homenodes, parse for xp's, subtract and return diff. Return LWP::UserAgent error message if problem fetching. =head1 REQUIRED ARGUMENTS first_monk_nick second_monk_nick =head1 OPTIONS proxy (http://proxyhost.tld:port_num) =head1 AUTHOR ybiC =head1 KNOWN BUGS $xp not defined if check thepen's xp. Works fine for NodeReaper, so not as simple as negative rep. Please read CAVEATS for other potential issues of note. =head1 SEE ALSO perl(1), Tie::IxHash(3), LWP::UserAgent(3), HTML::TokeParser(3). =cut

Use:  <p> text here (a paragraph) </p>

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 How to display code and escape characters are good places to start.
