El xml es muy simple (estoy haciendo simplemente pruebas)

<?xml version="1.0" encoding='ISO-8859-1'?>
<?xml-stylesheet href="USUA_date-time.xsl" type="text/xsl"?>

<item>
<pubdate>2007-07-24</pubdate>
</item>

No se si alguien me podra ayudar, pero de todas formas gracias, y no os asusteis si veis alguna burrada que me falta o asi, porque soy nueva en este tipo de lenguajes y estoy bastante perdida :p
Gracias de nuevo.

La cosa es que me saca en pantalla todos los meses y yo solo quiero que me saque el que corresonda al numero que le mando (ejemplo: 11->noviembre)
