1. HTML and PHP

HTML

Create a <form >. In the <form > create a textbox and a button. The textbox is use to enter the feed URL.

PHP

Assigned default feed URL in $url variable, its value gets updated when <form > is submitted.

Using simplexml_load_file() function check URL is valid or not. If URL is valid then it returns an Object after interpreting the XML.

Loop over the Object to get content.
