Just use a recursive routine to drill down. Witness:

my @array=(['john','tom','peter'],['rose','teak'],['car','truck','jeep
+'],['trees','plants'],['good','bad','ugly']);
my @arrayindex=(3,1);

my @wanted = @array[@arrayindex]; # get slice
show(@wanted);
sub show {
  if (ref @_[0]) { # still recursing
    for (@{+shift}) {
      show(@_, $_);
    }
  } else { # end case
    print "@_\n"; # do what you want with the results here
  }
}

This prints:

trees rose
trees teak
plants rose
plants teak

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.
