I need to pars an xmlfile,using perl. So basically I want to convert this xml file to some data structure like hashes and arrays.by this code now I can have access to the all nodes except for graphics node and its elements.

XML file:

   
 <pathway name="path:ko00010" org="ko" number="00010"
    title="Glycolysis / Gluconeogenesis"
    image="http://www.kegg.jp/kegg/pathway/ko/ko00010.png"
    link="http://www.kegg.jp/kegg-bin/show_pathway?ko00010">
    <entry id="13" name="ko:K01623 ko:K01624 ko:K01622 ko:K16306"
        link="http://www.kegg.jp/dbgetbin/www_bgetK01623+K16306">
        <graphics name="K01623..." fgcolor="#000000" bgcolor="#BFBFFF"
          type="rectangle" x="483" y="404" width="46" height="17"/>
    </entry>
  </pathway>

    use XML::LibXML;
    use strict;
    use warnings;
    my $parser = new XML::LibXML;
    my $xmlp= $parser -> parse_file("ko00010.xml");
    my $rootel = $xmlp -> getDocumentElement();
    my $elname = $rootel -> getName();
    my @rootelements=$rootel -> getAttributes();
    foreach my $rootatt(@rootelements){
        my  $name = $rootatt -> getName();
        my $value = $rootatt -> getValue();
        print " ${name}[$value]\n ";
    }
    
    my @kids = $rootel -> childNodes();
    foreach my $child(@kids) {
        my $elname = $child -> getName();
        my @atts = $child -> getAttributes();
        foreach my $at (@atts) {
            my $name = $at -> getName();
            my $value = $at -> getValue();
            print " ${name}[$value]\n ";
    
        }
