While the DOM tree allows for fast and omnidirectional navigation, building its abstract representation in the first place can be time-consuming. An abstract representation of the entire document tree is stored in memory, giving you random access to the individual elements. It defines a handful of standard operations for traversing and modifying document elements arranged in a hierarchy of objects. The DOM is arguably the most straightforward and versatile model to use.

Both XML and HTML belong to the same family of markup languages, which makes parsing XML with the DOM possible. You might have already heard about the DOM because web browsers expose a DOM interface through JavaScript to let you manipulate the HTML code of your websites. Historically, the first and the most widespread model for parsing XML has been the DOM, or the Document Object Model, originally defined by the World Wide Web Consortium (W3C). To get the most out of this tutorial, you should already be familiar with XML and its building blocks, as well as how to work with files in Python.

By the end of it, you’ll be able to pick the right XML parser for a given problem.

You can use this tutorial as a roadmap to guide you through the confusing world of XML parsers in Python.

Use safe XML parsers to eliminate security vulnerabilities.

Parse XML documents declaratively using data binding.

Use the XML parsers in the standard library.

It’s worthwhile to familiarize yourself with the available tools. Jokes aside, all XML parsers have their place in a world full of smaller or bigger challenges. Luckily, the Python community solved this surplus problem by creating even more XML parsing libraries. At the same time, the standard library follows the batteries included motto by letting you choose from not one but several XML parsers. On the one hand, the Zen of Python promises only one obvious way to achieve your goal. If you’ve ever tried to parse an XML document in Python before, then you know how surprisingly difficult such a task can be.
