Cargar XML desde un servidor externo

Hola, me descarge unos ejemplos de prueba para cargar un XML desde otro servidor diferente al mio pero cuando cambio la ruta del XML no me funciona, los archivos que tengo son estos:

Alguien sabe que he de cambiar para que cuando cambie la ruta del XML que hay en el codigo html por la del XML que quiero utilizar funcione?

Mod: Los códigos deben ir en etiquetas GeSHi
