Develop practical XML skills by learning to design, structure, and validate documents for reliable data representation and exchange. This beginner-to-intermediate course introduces markup languages, XML architecture, data sharing, interoperability, and the relationship between XML and HTML. You’ll also examine specialized applications, including Chemical Markup Language, and use comments and processing instructions to organize data clearly.

As you progress, you’ll differentiate character data types, define reusable general and parameter entities, and construct Document Type Definitions (DTDs). Through more than 25 progressively complex examples, you’ll declare elements and attributes, apply mixed content models and repetition operators, create nested structures and self-closing tags, and validate XML syntax and DTD compliance. Designed for aspiring developers, data professionals, technical writers, and anyone seeking practical XML knowledge, this course follows a focused learn-by-doing progression. By the end, you’ll be able to create well-formed XML documents, define valid content structures, troubleshoot syntax and tag usage, and maintain clear, reusable XML for data management and communication. Enroll to build confidence with XML markup and DTD validation through structured, hands-on practice.
