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

Dear All,

I was using code that I found on PerlMonks page but can't seem to figure out how to use it. I have a set of hash reference created with;

$idx = 0; foreach $n (@IDs) { push @{$An{$n}->{b}} , $bb[$idx]; push @{$An{$n}->{c}} , $cc[$idx]; push @{$An{$n}->{e}} , $ee[$idx]; push @{$An{$n}->{d}} , $dd[$idx]; push @{$An{$n}->{f}} , $ff[$idx]; $idx++; }

How can I then for each $ID print values of corresponging position? Such as $ID[0], @{$An{$n}->{b}}[0]? etc. Btw is it a better practice to declare arguments with 'my' at the begining or just in code? I end up with a code ehader having declaration of 40+ variables (not always possible to do subs). Thanks for help.

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.
