xml.etree.ElementTree — The ElementTree XML API
January 29, 2026 - Writes the element tree to a file, as XML. file is a file name, or a file object opened for writing. encoding [1] is the output encoding (default is US-ASCII). xml_declaration controls if an XML declaration should be added to the file.

February 25, 2023Proper indentation for XML files
I'm not sure if there is one correct way to add indentation to the XML files, but it works. You can use that before saving the XML files. If there are some other features you'd want to use in XML file handling but are not present in the built in xml APIs of Python, you can use lxml, a third party module. More on reddit.com

April 8, 2025How to process / parse XML with Python
Best bet: Use lxml . There's a nice tutorial on the site, too . You can also use the built-in XML parser, either with ElementTree (common) or XML DOM (rarer) , or any other related library from the xml module , but most people prefer lxml, as it's much more powerful (and in parts, compatible with ElementTree).

October 22, 2017what config file format do you prefer?
I use INI files with JSON values and a bit of custom parsing, so that I can load substructures. For example:
Title = "Foo" [Logging] StdLog = null ErrLog.Level = "WARN"
gets parsed into {"Title": "Foo", "Logging": {"StdLog": None, "ErrLog": {"Level": "WARN"}}}.
The configparser module is a bit clunky and.. unpythonic, but usable.

Python XML Parser Tutorial | ElementTree and Minidom Parsing | Edureka
December 5, 2024 - Python allows parsing these XML documents using two modules namely, the xml.etree.ElementTree module and Minidom (Minimal DOM Implementation). Parsing means to read information from a file and split it into pieces by identifying parts of that particular XML file. Let’s move on further to see how we can use these modules to parse XML data. This module helps us format XML data in a tree structure which is the most natural representation of hierarchical data.

By specifying encoding and xml_declaration in the second example, a custom-formatted XML file is created with an XML declaration at the top.

Use Python's error handling mechanisms (try-except blocks) to diagnose and manage parsing errors gracefully. ElementTree does not support pretty-printing directly, but you can use xml.dom.minidom to parse the XML string and then use its toprettyxml() method to format the XML for readability.

r/PythonLearning on Reddit: Proper indentation for XML files
April 8, 2025 -
I'm working on a Python script that reads data from an Excel file and generates individual XML files based on each valid row. The script extracts various fields, handles date formatting, and builds a structured XML tree for each record. For certain entries, I also include duplicate tags with additional details (e.g., a second <Description> tag with a formatted date).
Now, I want the XML output to be properly indented for readability. I came across xml.etree.ElementTree.indent(tree, space=' ', level=0) as a possible way to format the XML. Is this the correct and recommended method to add indentation to the XML files I'm creating? If so, where exactly in my code should I use it for best results? Also im pretty new to python, like this would be my first time doing something on python apart from v basic code in the past. If anyone knows some resources that they think could help, i would really appreciate that too. Any help is appreciated :)
