So, you've got an XML file and need to make sense of it using Python? Welcome to the club! Parsing XML in Python might sound intimidating at first, but fear not—Python offers a variety of tools to handle XML parsing efficiently. Whether you're dealing with configuration files, APIs, or data exchange formats, Python's XML parsing capabilities have got you covered.
In this guide, we’ll explore how to parse XML in Python using different methods, from built-in modules to third-party libraries. We’ll cover everything from reading an XML file in Python to converting XML to a dictionary and handling errors along the way.
By the end of this post, you'll be a Python XML parsing expert (or at least you'll be able to impress your colleagues with your newfound XML skills).
XML (eXtensible Markup Language) is a widely used format for structuring data. Think of it as a hierarchical structure similar to JSON but with extra verbosity and those pesky angle brackets. It is a text-based format that uses tags to define elements, making it both human-readable and machine-readable.
XML is commonly used for:
One of the key benefits of XML is its ability to maintain a tree structure, allowing nested relationships between elements. This makes it especially useful for representing hierarchical data, such as organizational charts, product catalogs, or file directory structures.
However, XML can be verbose and sometimes unnecessarily complex compared to more lightweight formats like JSON. But don't worry—Python has several powerful libraries to help you parse and manipulate XML efficiently!
Since Python is all about automation and data manipulation, having the ability to read XML in Python and extract meaningful information is essential. Whether you're working with XML configuration files, API responses, or large datasets, knowing how to parse XML effectively will save you a ton of time and effort.
Now, let’s dive into the different ways to parse XML in Python!
If you're looking for the simplest way to parse XML in Python, the xml.etree.ElementTree module is your best friend. It provides a tree structure representation of XML, making it easy to navigate and extract data.
Reading an XML File with ElementTree
Parsing an XML String
If you already have an XML string, you can parse it directly:
Accessing XML Attributes
You can also access XML attributes like this:
ElementTree is simple and lightweight but has some limitations, especially with handling large XML files or advanced XML structures.
If you like pretty-printed XML and a more human-friendly approach, xml.dom.minidom is a good choice.
Parsing XML with minidom
minidom is great for pretty-printing XML, but it’s not as efficient for large files.
If you need something more powerful and feature-rich, lxml is the way to go. It’s faster than ElementTree and supports XPath, making XML parsing much more flexible.
Installing lxml
Parsing XML with lxml
With lxml, you can easily query elements using XPath, making it a powerful Python XML parser.
If you love working with dictionaries, you’ll love xmltodict. It converts XML into a Python dictionary, making it super easy to work with structured data.
Installing xmltodict
Parsing XML to a Dictionary
No more manually traversing tree structures—just Python dictionary magic!
You might know BeautifulSoup for HTML scraping, but it also handles XML parsing in Python quite well.
Installing BeautifulSoup
Parsing XML with BeautifulSoup
BeautifulSoup is great when working with messy XML, but it’s not the most efficient XML parser Python offers.
Sometimes, XML files can be malformed or have encoding issues. You’ll want to catch these errors gracefully.
Always handle errors properly when dealing with real-world XML files to avoid unexpected crashes.
You can also use Pandas read XML functionality to convert XML into DataFrames for easier analysis.
Installing Pandas XML support
Reading XML into Pandas
This is perfect when dealing with structured data that needs analysis.
If you want to test your XML parsing without writing code locally, there are online XML parsers that can help:
These tools are useful for quick XML debugging.
There you have it! We covered multiple ways to read XML in Python, from built-in libraries like ElementTree and minidom to powerful tools like lxml, xmltodict, and BeautifulSoup. You even learned how to convert XML to a Python dictionary, read XML into Pandas, and handle errors.
Next time someone asks, "How do you parse XML in Python?", you'll have plenty of answers (and maybe a joke or two about XML verbosity).
So, go forth and parse XML like a pro!

Yes! Python indeed has a built-in XML parser. This module is called xml.etree.ElementTree.
Lxml and minidom are the usual go-to libraries for parsing XML in Python. Another popular one is BeautifulSoup due to its ease of use and versatility.
Simply employ the built-in xml.etree.ElementTree function and you are good to go! Instructions and code examples can be found above.
To decode an XML file in Python, you can use the built-in xml.etree.ElementTree module. It can read and parse the XML file, allowing you to navigate its structure.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
