( #3333=superdoc: print w/replies, xml ) Need Help??
Hello. I only have a suggention on the IP matching part. I've always found myself using the below extra-large regexp, courtesy of Mastering Regular Expressions.
my @ips = qw( 123.555.333.222666 ); foreach my $ip (@ips) { my $f = undef; if($ip =~ m/^(?!0+\.0+\.0+\.0) ([01]?\d\d?|2[0-4]\d|25[0-5]) \.([01]?\d\d?|2[0-4]\d|25[0-5]) \.([01]?\d\d?|2[0-4]\d|25[0-5]) \.([01]?\d\d?|2[0-4]\d|25[0-5])$/x ) { $f =1; } print 'Is', $f ? "" : 'n\'t', " valid and/or usable IP: $ip \n" }
When run produces:
Is valid and/or usable IP: Isn't valid and/or usable IP: Isn't valid and/or usable IP: Isn't valid and/or usable IP: 123.555.333.222666
Update: changed code to better illustrate its usefulness.

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