XML Schemas
In this tutorial, you'll learn about XML schemas and how to use them in your XML documents. We'll look at the XML schema data types and their categories and then explore how to create simple and complex data types.

The XML Document Object Model
The XML Document Object Model (DOM) is a platform-neutral and language-neutral interface that allows developers to create applications and scripts to access and update the content, style, and structure of XML documents.

Structure of an XML Document
The structure of an XML document can be defined by two standards. The first standard is the XML specification, which defines the default rules for building all XML documents.

Markup Languages
A markup language uses special notation to mark the different sections of a document. In HTML documents, for example, angle brackets (<>) are used to mark the different sections of text.

Digging Deeper into XML Documents
In this tutorial, you'll learn, how to document your XML code with comments, how characters of text are encoded in XML, all about entities and how they are used, why notations make it possible to use certain kinds of entities

Using XML Schema
This tutorial introduces you to XML Schema and shows you how to create XSD schemas that can be used to validate your own documents

Defining Data with DTD Schemas
This tutorial introduces you to schemas, including the two major types that are used to define data for XML documents. This tutorial explores the inner workings of DTDs and shows you how to create DTDs from scratch.

Introduction of DTD (Document Type Definition) Syntax
DOCTYPE Declaration Statement ELEMENT Declaration Statement ATTLIST Declaration Statement ENTITY Declaration Statement Sample XML File with DTD Statements - dictionary_dtd.xml

XML Tutorials - XSD (XML Schema Definition) Syntax
Simple XML Elements with Pre-defined Data Types Simple XML Elements with Extended Data Types Complex XML Elements Simple Content XML Elements Empty XML Elements Anomymous Data Types Sample XSD File - dictionary.xsd

Getting to Know XML
XML's usage is continuing to grow quickly as both individuals and companies realize its potential. However, in many ways XML is still a relatively new technology, and many people, possibly you, are just now learning what it can do for them. Unlike some other software technologies such as HTML or even Java, XML is a little fuzzier in terms of how it is applied in different scenarios. Just as it's difficult to look at a person and grasp how their DNA makes them who they are, it can also be challenging to look at an application and get a grasp for how XML fits into the equation. This tutorial introduces you to XML and gives you some insight as to why it was created and what it can do.

Creating XML Documents
In this tutorial, you'll learn - The basics of XML - How to select an XML editor - How to create XML documents - How to view XML documents Similar to HTML, XML is a technology that is best understood by working with it. I could go on and on for pages about the philosophical ramifications of XML, but in the end I'm sure you just want to know what you can do with it. Most of your XML work will consist of developing XML documents, which are sort of like HTML web pages, at least in terms of how the code is generally structured.
