Handling XML data
Views: 23887
Introduction
This tutorial was originally posted on the old site on 20th December, 2007.
XML, Extensible Markup Language, is a general-purpose markup language which can be used for storing arbitrary data in a structured way. It is often used for sharing data between applications and a common usage of XML is for instance RSS feeds.
With the emerge of PHP 5, support for handling XML data has greatly improved and in this tutorial we will take a look at the features in PHP 5 which we can use to parse, alter and create XML documents. At the end of the tutorial we will also take a look at how you can create an RSS feed without writing a single line of XML and then we will make it into a reusable class which you can implement in your own applications. Additionally we'll create a really simple RSS reader.
Basic knowledge of XML is a prerequisite for this tutorial. Knowledge of XPath would be a good idea as it will be used a bit in this tutorial, however, this is not entirely important. Furthermore, OOP knowledge is a requirement as well.
Right, let's go to the next page and get started...
