( #3333=superdoc: print w/replies, xml ) Need Help??

You could just rejoin your strings after spliting and sorting and then compare them:

#! perl -slw use strict; sub reorder { my $string = shift; return join ',', sort{ $a cmp $b } split ',', $string; };; my $string1 = '~cake,pastry'; my $string2 = 'pastry,~cake'; my $string3 = 'cake,pastry'; print "$_->[ 0 ] eq $_->[ 1 ]", reorder( $_->[ 0 ] ) eq reorder( $_->[ 1 ] ) ? ' match ' : ' dont match' for [ $string1, $string2 ], [ $string1, $string3 ], [ $string2, $string3 ]; __END__ [ 8:16:14.39] P:\test>junk2 ~cake,pastry eq pastry,~cake match ~cake,pastry eq cake,pastry dont match pastry,~cake eq cake,pastry dont match

Not hugely efficient, but probably not too bad if there are only a few elements in your strings.


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.

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.
