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

You want to sort the words in the regular expression by descending length :) Or alternatively, use \b to match only whole words:

my %trans = (zero => 0, one => 1, ones => 11, two => 2, three => 3); my $words_re = join "|", map quotemeta, sort { length($b) <=> length($ +a) } keys %trans; $string =~ s/\b($words_re)\b/$trans{lc $1}/ig;

Otherwise, it could be that one matches before ones.

Update: choroba spotted that the length($b) and length($a) were missing

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.
