I am trying to add an attribute to existing XML, using XML::LibXML.

    <arbre>
      <branche name="courbe" >
        <description>
          <![CDATA[une belle branche]]>
        </description>
        <feuilles>
          <fleur color="blue" order="1" />
          <fleur color="white" order="2" />
          <fleur color="yellow" order="3" />
        </feuilles>
      </branche>
      <branche name="droite" >
        <description>
          <![CDATA[une branche commune]]>
        </description>
        <feuilles>
          <fleur color="purple" order="1" />
          <fleur color="green" order="2" />
        </feuilles>
      </branche>
    </arbre>

That I am trying to transform into :

    <arbre>
      <branche name="courbe" type="conifere">
        <description>
          <![CDATA[une belle branche]]>
        </description>
        <feuilles>
          <fleur color="blue" order="1" />
          <fleur color="white" order="2" />
          <fleur color="yellow" order="3" />
        </feuilles>
      </branche>
      <branche name="droite" type="resineux">
        <description>
          <![CDATA[une branche commune]]>
        </description>
        <feuilles>
          <fleur color="purple" order="1" />
          <fleur color="green" order="2" />
        </feuilles>
      </branche>
    </arbre>

Notice the type attribute in branche tag.
So far I have the following :

    #!/usr/bin/env perl -w
    
    use strict;
    use XML::LibXML;
    
    $parser = XML::LibXML->new();
    $dom    = $parser->load_xml();
    # now I do what?
    exit 0;

I know how to do this with XML::Simple, but someone told me that the use of this librairie is not recommended.
Which might be true because I have encodings and stripped CDATA problems

From what I understand from the documentation $dom is a document object which has a method called createAttribute that I might be able to use.
Any solution?.
Thanks
