XML is a set of rules for defining semantic tags that describe the structure and meaning of a document.
The user of XML chooses the names and placement of the tags to convey the nature of the data stored in a document. XML can be used to markup any data file to make it easier to understand and process.
In addition, it has been applied to many special domains of data: mathematics, music, vector graphics, the spoken word, financial data, chemical symbols, and web pages among others.
Here’s our recommended free tutorials to help you master XML. If you need more in-depth material, try our recommended free XML books.
1. The XML Revolution by Anders Moller and Michael I. Schwartzbach
This set of tutorials explain the following topics: HTML and XML, Namespaces, XInclude, and XML Base, DTD, XML Schema, and DSD , XLink, XPointer and XPath, XSL and XSLT, XQuery, DOM, SAX, and JDOM, World Wide Web Consortium.
2. Using XML Technologies Lecture Notes
The lecture notes covers the following topics: Introduction to XML, Document Type Definitions, Document Object Model, XML Schemas, Simple API for XML, XSL Transformations, Relax NG, XQuery, JDOM, XML-RPC.
3. XML and Databases by Ronald Bourret
This paper gives a high-level overview of how to use XML with databases. It describes how the differences between data-centric and document-centric documents affect their usage with databases, how XML is commonly used with relational databases, and what native XML databases are and when to use them.
4. Learn XML in Y minutes by João Farias and contributors
XML is a markup language designed to store and transport data. It is supposed to be both human readable and machine readable.
Unlike HTML, XML does not specify how to display or to format data, it just carries it.
5. XML for the absolute beginner by JavaWorld
This is a guided tour from HTML to processing XML with Java.
6. XML Basics
This note covers the following topics: introduction, the anatomy of XML document, components of XML document, XML validation, rules for well-formed XML document, XML DTD, more XML components, references, reading list.
