( [id://3333]=superdoc: print w/replies, xml ) Need Help??

It works, so long as each element is 0 padded, and you're using consistent delimiters between the two items to be compared. The following won't work:

'2004-9-1' lt '2004-10-1' '2004/09/01' lt '2004-09-01'

I typically get around the second issue by stripping out all non-digits, and then comparing. The first one I haven't found a simple one-line solution for, as I get stuff that's both delimited and run together. If it was always delimited:

sub normalize_date { return join( '', map { sprintf( '%02i', $_ ) } sp +lit (/\D+/, $_[0]) ) } sub compare_dates { return normalize_date($_[0]) cmp normalize_date($_ +[1]) }

hmm ... I guess this _would_ work for me, as the non-delimited stuff I get is always 0 padded.

Title:
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.
