I think maybe we're misunderstanding each other somehow. I think the reason the OP's search loop is not finding anything in the array is because each of the array keys has an extraneous newline at the end. Take that off (with chomp), and it should be fine.

use Test::More 'tests' => 4; my $line; my %faclist; $line = "17\n"; $faclist{$line} = ""; $line = "23\n"; chomp $line; $faclist{$line} = ""; ok( ! exists $faclist{17}, 'number 17 does not exist' ); ok( ! exists $faclist{'17'}, 'string 17 does not exist' ); ok( exists $faclist{23}, 'number 23 exists' ); ok( exists $faclist{'23'}, 'string 23 exists' );

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.
