XML Processing: DOM Parser, XPath & XQuery (FLWOR) Explained (Sinhala) | Part 04

Welcome to the fourth episode of the Semantic Web Technologies complete course by Smart Syntax! 🚀

In this video, we move from defining XML to processing and querying it. We learn how to parse XML documents using the DOM Parser in JavaScript, how to navigate XML trees using XPath, and how to query data efficiently using XQuery and FLWOR expressions.

මෙම වීඩියෝව මගින් XML දත්ත හැසිරවීම (Processing) සහ අවශ්‍ය දත්ත තෝරා ගැනීම (Querying) ගැන සරලව සිංහලෙන් පැහැදිලි කරයි. JavaScript මගින් XML Parse කරන ආකාරය, XPath භාවිතයෙන් දත්ත සොයාගන්නා ආකාරය සහ XQuery FLWOR මගින් සංකීර්ණ දත්ත ලබාගන්නා ආකාරය මෙහිදී සාකච්ඡා කෙරේ.

📌 In this video, we cover:

XML Parsing: Using the DOM (Document Object Model) Parser in JavaScript to read XML strings.
XPath (XML Path Language): Navigating through elements and attributes in an XML document (Nodes, Axes, Predicates).
XQuery: A powerful functional language for querying XML data.
FLWOR Expressions: The SQL-like syntax of XQuery (For, Let, Where, Order by, Return).
