Constructing XML Trees with Tokenizers and Stacks

Have you ever wondered how software applications read, interpret, and manipulate structured hierarchical data behind the scenes? Understanding how to parse markup languages is a foundational skill that bridges the gap between raw text and structured data models. This text-only course guides you through the process of building an XML parser from scratch, transforming unstructured document strings into navigable tree structures. By working through this course, you will gain a deep, practical understanding of how compilers and parsers process hierarchical relationships using fundamental computer science concepts. You will transition from writing basic scripts to designing robust parsing logic that mirrors industry-standard tools. What you'll learn: - Understand the core specifications of XML documents and hierarchical tree structures - Implement a custom tokenizer class to break raw text into meaningful lexical tokens - Utilize stack data structures to track nested parent-child relationships efficiently - Construct a robust node class to represent elements, attributes, and text content - Parse valid XML documents into fully navigable, memory-efficient tree structures - Apply modern debugging and error-handling techniques to catch malformed structures We begin with foundational definitions of tree architectures, document object models, and tokenization principles. From there, you will read step-by-step explanations and analyze clean code implementations that build the tokenizer, the stack tracking system, and the final tree constructor. This course is designed for beginner to intermediate programmers, software engineering students, and self-taught developers who want to strengthen their algorithm and data structure skills. No prior parsing experience is required; familiarity with basic programming concepts like loops, recursion, and classes is all you need to get started.
