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

Yeah, that's doable. I can also think of doing it without having everything inside the loop ..

#!/usr/bin/perl use strict; use warnings; # 2022-0125: Handle First and List iems differently that everything # in between .. { my @keys = qw/q w e r t y u i o p/; print "First is $keys[0] ..\n"; foreach my $k ( @keys[1..(scalar @keys -2)] ) { print "In the middle: $k\n"; } print "Finally, we have $keys[-1].\n"; }
This produces the output
First is q .. In the middle: w In the middle: e In the middle: r In the middle: t In the middle: y In the middle: u In the middle: i In the middle: o Finally, we have p.
But I like your solution of using an Iterator -- then it has the job of handling the 'first' and 'last' issues.

  • 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.
