I may be missing something but if the last line of your desired output is this1 belongs to h8this13 then it seems logical that you would also have this2 belongs to h5this21 and this2 belongs to h6this23. Anchoring the match to the end of the string drops your last desired line. Perhaps you could clarify your requirement.

use strict; use warnings; my @arr1 = qw{ this1 this2 this11 this21 this23 }; my @arr2 = qw{ h2this1 h3this2 h5this21 h6this23 h8this13 }; my @arr1Rx = map { [ $_, qr{$_\z} ] } @arr1; foreach my $e2 ( @arr2 ) { foreach my $e1 ( @arr1Rx ) { print qq{$e1->[ 0 ] belongs to $e2\n} if $e2 =~ $e1->[ 1 ]; } }

The output

this1 belongs to h2this1 this2 belongs to h3this2 this21 belongs to h5this21 this23 belongs to h6this23

I hope this is of interest.

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.
