Muchas gracias por tus sugerencias pero en las páginas que me comentabas no he encontrado nada mejor que el que tengo. En este tiempo he conseguido cortar el javascript y ya no tengo que copiarlo entero en cada página html pero sigo con un problema en la actualización de las URLs: me sigue tomando como raíz para construir las URLs a las que dirigirse a través de los enlaces de los elementos hijos y sub-hijos del árbol la de la página desde la que se llama.
Estoy segura que el problema deriva del propio código que en alguna parte le establece que tome la dirección de la página que lo llama pero he dado mil repasos al mismo y no acabo de verlo. También es cierto que tengo muy poca experiencia con javascripts por lo que seguro que si alguien le echa un vistazo, enseguida dará con la modificación que tengo que poner para que las direcciones urls de los enlaces a demás páginas puedan estar en un único fichero js y actualizando éste se actualice en todas las que lo llaman.
Os pongo el código a continuación:

En este ejemplo tenemos en cuenta que la página "Nodo_padre.html" está en el directorio raíz y que a su mismo nivel hay dos subcarpetas llamadas "Hijo1" e "Hijo2" que contienen una página cada denominadas "Nodo_hijo1.html" y "Nodo_hijo2.html" respectivamente.
Culaquier ayuda que podais darme será bien recibida. Muchas gracias a tod@s !!
