How to Effectively Interpret Simple XML to HTML with PHP

When developing web applications, it's common to receive data from a server in XML format. However, the challenge often lies in extracting and displaying this data in a user-friendly manner on your web pages. For instance, you may find yourself in a situation where you receive a Simple XML response from a server and only want to display specific elements such as product titles, prices, and promotional links. In this guide, we will explore a straightforward approach to help you transform Simple XML into well-structured HTML using PHP.

Understanding the Problem

Imagine you're building an e-commerce application where you query a product database via an API and receive a response in Simple XML. The response contains numerous details about various products, but you only want to extract and display certain pieces of information, such as:

Product Title

Sale Price

Promotion Link

From the XML response received, your goal is to present only the needed data in clean HTML format. Let's visualize how the data looks in XML and how we can convert this into an understandable HTML format.

Example of the XML Response
