Overview

XML Course

Learn XML for configs and markup: syntax, namespaces, Maven/Android files, formatting vs validation, and debugging.

This course teaches XML as a structured text format for configs, build files, and markup—not as a generic database or programming language. You will learn element/attribute structure, namespaces, Maven POM and Android manifest patterns, the difference between formatting and validation, and a debugging workflow before you ship XML to production.

Who this course is for

  • Backend and platform engineers editing Maven POM or integration configs
  • Mobile developers maintaining Android manifests and resource XML
  • Full-stack developers who hit XML parse errors from build tools or CI

What you will learn

  1. Elements, attributes, declarations, and where XML still matters
  2. Well-formed syntax and namespace prefixes (xmlns)
  3. Practical patterns in Maven POM and Android manifest files
  4. When formatting helps—and what validation does not guarantee
  5. A validate → fix → format workflow with editor error markers

Use the related XML Formatter to experiment locally. Valid XML proves syntax—not that a manifest is correct for your app or cluster.
