XML Course

Master XML from the ground up — syntax, validation, transformation, querying, and programmatic parsing. This course covers every major XML technology used in professional software development, including XSD, XSLT, XPath, and XQuery. Whether you're integrating data systems or designing enterprise schemas, you'll gain the hands-on skills employers need.

Dedika for students

What your team will master:

You'll start with core XML syntax and document structure, then move into validation using both DTD and XSD. From there, you'll learn to navigate documents with XPath, transform them with XSLT, and query XML data using XQuery. The course also covers DOM, SAX, and StAX parsing APIs so you can integrate XML processing into real applications. You'll explore namespaces, XML security standards, web services, and JSON interoperability. By the end, you'll have a complete, professional-grade XML skill set ready for immediate use.

Course content

8 Chapters • 41 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Introduction to XML Fundamentals

    Addresses text content, whitespace handling, and reserved characters. Prevents common encoding mistakes when authoring XML.

  • Lesson 2 • Core XML Syntax Rules

    Teaches the mandatory syntax rules that make a document well-formed. Mastery here prevents parsing errors throughout the course.

  • Lesson 3 • XML Document Structure

  • Lesson 4 • What XML Is and Why It Matters

    Covers XML's origin, design goals, and contrast with HTML. Establishes context for every subsequent technical topic in the chapter.

Chapter 2See details

Validating XML with DTD

  • Lesson 1 • Declaring Attributes in a DTD

    Covers ATTLIST declarations, attribute types, and default values. Completes the DTD skill set needed to validate real-world documents.

  • Lesson 2 • Declaring Elements in a DTD

    Teaches element declarations, content models, and occurrence indicators. Students write declarations that mirror real document structures.

  • Lesson 3 • Purpose and Scope of Validation

    Distinguishes well-formed from valid XML and explains why validation matters. Sets the rationale for learning DTD before more advanced schema languages.

  • Lesson 4 • Internal and External DTDs

    Explains how to embed a DTD inside a document or reference an external file. Students choose the right approach for different project scenarios.

  • Lesson 5 • Entities and Notations in DTDs

    Introduces general, parameter, and unparsed entities plus notation declarations. Extends DTD authoring to handle reusable content and binary references.

Chapter 3See details

XML Schema Definition (XSD) Essentials

  • Lesson 1 • Schema Extension and Restriction

    Covers type derivation by extension and restriction to build type hierarchies. Students create flexible schemas that accommodate evolving data requirements.

  • Lesson 2 • Complex Types and Content Models

    Teaches complex type definitions with sequence, choice, and all compositors. Students model nested document structures accurately.

  • Lesson 3 • Simple Types and Built-in Datatypes

    Covers XSD's built-in primitive and derived types for element and attribute values. Students apply correct types to enforce data integrity.

  • Lesson 4 • Reusable Schema Components

    Explains named types, element groups, and attribute groups for schema reuse. Reduces redundancy and improves schema maintainability.

  • Lesson 5 • Modular Schema Design

    Teaches include, import, and redefine directives for multi-file schema projects. Students organize large schemas into maintainable, modular components.

  • Lesson 6 • XSD Structure and Namespaces

    Introduces the XSD document skeleton, target namespace, and namespace declarations. Provides the structural foundation for all subsequent schema authoring.

Chapter 4See details

Navigating XML with XPath

  • Lesson 1 • XPath Functions and Operators

    Surveys string, numeric, boolean, and node-set functions built into XPath. Students combine functions with path expressions for complex queries.

  • Lesson 2 • Location Paths and Axes

    Teaches absolute and relative location paths using all XPath axes. Students navigate any part of an XML tree with precision.

  • Lesson 3 • Predicates and Filtering Nodes

    Covers predicate syntax for filtering node sets by position, value, or condition. Enables targeted selection within large XML documents.

  • Lesson 4 • XPath Data Model and Node Types

    Introduces the XPath tree model and its seven node types. Understanding node types is prerequisite to writing correct path expressions.

  • Lesson 5 • XPath 2.0 and 3.1 Enhancements

    Highlights key additions in XPath 2.0 and 3.1 over the 1.0 baseline. Prepares students for modern XSLT and XQuery environments.

Chapter 5See details

Transforming XML with XSLT

  • Lesson 1 • XSLT Stylesheet Structure

    Explains the root stylesheet element, namespace declarations, and output method. Establishes the skeleton every XSLT stylesheet must follow.

  • Lesson 2 • Advanced XSLT Techniques

    Explores keys, grouping, and multi-document processing for complex transformations. Students handle real-world scenarios beyond simple one-to-one mappings.

  • Lesson 3 • Variables, Parameters, and Expressions

    Covers xsl:variable, xsl:param, and XPath expressions within stylesheets. Students write dynamic, reusable transformation logic.

  • Lesson 4 • Template Rules and Pattern Matching

    Teaches xsl:template, match patterns, and the built-in template rules. Students control which nodes are processed and how output is generated.

  • Lesson 5 • Control Flow in XSLT

    Introduces xsl:if, xsl:choose, and xsl:for-each for conditional and iterative output. Enables data-driven transformations based on document content.

  • Lesson 6 • Generating Output Elements and Text

    Teaches xsl:element, xsl:attribute, xsl:text, and xsl:value-of for precise output construction. Students produce well-formed output documents from any input.
