+# LEE UN ARCHIVO XML EL CUAL CONTIENE UN ARRAY DE EMPLEADOS, LOS MOSTRARÁ POR PANTALLA
+
+Se trabaja con la ayuda de DOM para así poder obtener la lista de los empleados que se encuentran el archivo XML.

+RESULTADO:
+
+```
+Número de empleados: 3
+
+ID del empleado: 1
+Apellido: Martinez
+Departamento: 10
+Salario: 1000.33

+ID del empleado: 2
+Apellido: Garcia
+Departamento: 11
+Salario: 2000.34
+
+ID del empleado: 3
+Apellido: Navarro
