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

Building on the correction by Anonymous Monk above, the following code gives you a hash in which each entry has a vendorUniqueKey as the key and the corresponding name as the value:

#! perl use strict; use warnings; use Data::Dumper; use XML::Simple; my $xmldoc = XMLin("dsys.xml"); my $vendors = $xmldoc->{'Catalog'}->{'Vendors'}; my %vendors = %{ $vendors->{'Vendor'} }; my %unique_vendors; while (my ($outer_key, $outer_value) = each %vendors) { if (ref($outer_value) eq 'HASH') { my ($inner_key, $inner_value) = each %$outer_value; if ($inner_key eq 'vendorUniqueKey') { $unique_vendors{$inner_value} = $outer_key; } else { warn "Inner key is not 'vendorUniqueKey'"; } } else { warn "Outer value is not a hash reference"; } } print Dumper(\%unique_vendors);

Output:

$VAR1 = { 'BETASYS' => 'Beta Systems Software', 'BMC' => 'BMC Software', 'ALLENGRP' => 'Allen Systems', 'AONIX' => 'Aonix North America' };

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.
