( #3333=superdoc: print w/replies, xml ) Need Help??
use strict; use XML::Rules; my $parser = XML::Rules->new( stripspaces => 7, rules => { substrate => sub { 'substrate' => $_[1]->{id}}, product => sub { '@products' => $_[1]->{id}}, reaction => sub { my %reactions; foreach (split / /, $_[1]->{name}) { $reactions{$_} = { substrate => $_[1]->{substrate}, pr +oducts => $_[1]->{products}}; } return '%reactions' => \%reactions; }, graphics => '', entry => sub { my @reactions = split ' ', (delete $_[1]->{reaction}); $_[1]->{reactions} = \@reactions if @reactions; return '%entries' => {$_[1]->{id} => $_[1]} }, pathway => 'pass' }); use Data::Dumper; print Dumper($parser->parsefile('d:\temp\pon01100.xml'));

Here's an example of how you could tweak the data structure as it's being read. It gives you a hash containing the name, org, title, image and link from the root tag and a hash of entries and a hash of reactions. The reactions contain only the stuff you said you need, the entries contain the data from the <entry> tag with the list of reactions split and converted into an array.

Enoch was right!
Enjoy the last years of Rome.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
