Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new web page with name "planes.xml" is created, which contains following code.

Note : In xml any thing referenced using & is considered as entity.Hence need to remove & before c and p.

planes.xml :

<?xml version = "1.0" encoding = "utf-8"?>

<!-- planes.xml - A document that lists ads for

used airplanes -->
