Association PHP & XML

[nemesis_elite]

Bonjour à tous

J'ai trouvé un jeu php en opensource nommé Acetone, celui-ci emploi
quelques fichiers xml pour, par exemple, les PNJ ( personnage non jouable )
comme celui-ci

Code :

<?xml version="1.0"?>
<npc>
    <conditions>
        <questAwaiting>
            <true>rootC</true>
        </questAwaiting>
        <questA>
            <true>rootB</true>
        </questA>
    </conditions>
    <movement>
        <step>
            <x>10</x>
            <y>10</y>
        </step>
        <step>
            <x>11</x>
            <y>10</y>
        </step>

</npc>

N'ayant jamais eu l'idée d'utiliser ce type de fichier, j'aimerai savoir comment cela fonctionne et comment peut on faire pour le mettre en relation avec les pages php. :heuuu:

Merci d'avance
