Tutorial: XML stands for EXtensible Markup Language. In our XML tutorial you will learn what XML is and the difference between XML and HTML. You will also learn how to start using XML in your applications
.XML was designed to describe data and to focus on what data is.
HTML was designed to display data and to focus on how data looks. XML tags are not predefined. You must define your own tags
XML uses a Document Type Definition (DTD) or an XML Schema to describe the data.
XML with a DTD or XML Schema is designed to be self-descriptive . XML is a W3C Recommendation
.XML is not a replacement for HTML. XML and HTML were designed with different
goals. XML was designed to describe data and to focus on what data is. HTML was designed to display data and to focus on how data looks.
HTML is about displaying information, while XML is about describing information
At W3schools you will find thousands of cut-and-paste examples.
With our on-line HTML editor you can edit the examples and experiment with the code on-line.
Because time is valuable, we deliver quick and easy learning. At W3Schools, you can study everything you need to learn, in an accessible and handy format.
is XML: XML is a markup language for documents containing structured information.
Structured information contains both content (words, pictures, etc.) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.). Almost all documents have some structure.
A markup language is a mechanism to identify structures in a document. The XML specification defines a standard way to add markup to documents.The number of applications currently being developed that are based on, or make use of, XML documents is truly amazing (particularly when you consider that XML is not yet a year old)! For our purposes, the word "document" refers not only to traditional documents, like this one, but also to the miriad of other XML "data formats". These include vector graphics, e-commerce transactions, mathematical equations, object meta-data, server APIs, and a thousand other kinds of structured information
Java /XML Tutorial: the Java XML Tutorial, is an online manual that can quickly get you up to speed writing XML code and XML-based software for end-user applications. Using step-by-step walkthroughs and lots of code examples, the Tutorial is divided into sections that cover the following major
topics.This page covers the basics of XML. The goal is to give you just enough information to get started, so you understand what XML is all about. (You'll learn about XML in later sections of the tutorial.) We then outline the major features that make XML great for information storage and interchange, and give you a general idea of how XML can be used.
With XML: the basics of XML and gives you a guide to the acronyms associated with it. It also provides an overview of the JavaTM XML APIs you can use to manipulate XML-based data, including the Java API for XML Processing ((JAXP). To focus on XML with a minimum of programming, follow The XML Thread, below.In this part of the tutorial, we focus on the event-driven, serial-access mechanism for accessing XML documents, SAX. This is the protocol that most servlets and network-oriented programs will want to use to transmit and receive XML documents, because it's the fastest and least memory-intensive mechanism that is currently available for dealing with XML documents.
On the other hand, the SAX protocol requires a lot more programming than the Document Object Model (DOM). It's also a bit harder to visualize, because it is an event-driven model. (You provide the callback methods, and the parser invokes them as it reads the XML data.) Finally, you can't "back up" to an earlier part of the document, or rearrange it, any more than you can back up a serial data stream or rearrange characters you have read from that stream.
In this tutorial you will learn what XML is about. You'll understand the basic XML syntax. An you will know what's needed to make XML usable.
You won't be an XML expert after following this kickstart tutorial. But you'll understand the basics of XML. And you'll be able to understand XML Documents and most of XML DTD's.
XML is used to aid the exchange of data. It makes it possible to define data in a clear way.
Both the sending and the receiving party will use XML to understand the kind of data that's been sent. By using XML everybody knows that the same interpretation of the data is used.EDI (Electronic Data Interchange) has been for several years the way to exchange data between businesses.
EDI is expensive, it uses a dedicated communication infrastructure. And the definitions used are far from flexible.
XML is a good replacement for EDI. It uses the Internet for the data exchange. And it's very flexible
Skew XML Tutorial: This is a crash course in some essential concepts for software developers who are reading and writing XML documents on a regular basis. It is oriented toward people with some sort of programming background. The intended audience should already understand some basic things like what bits and bytes are, how to read hexadecimal numbers, what characters are, and they should be comfortable with phrases like "hierarchical data model".I wrote this document after having the realization, in early 2000, that every published XML reference I have seen does not adequately explain some fundamental concepts that, in my opinion, are essential to understand before trying to do any serious development with XML. It might seem strange that examples of how to write an XML document are not introduced until well into the tutorial. I feel strongly that the proper way to learn this material is to understand the founding concepts and principles first. Then the details of the syntax become almost incidental.
World value of XML: On the design front we needed to accurately project our corporate brand: Capco unites thought leadership with practical advice on improving the efficiency and profitability of our clients operating within the financial services industry. As such, projecting the right image is vital for our corporate success.
In terms of technology, we demanded a flexible content management system (CMS) which offered easy-to-use interfaces for content-contributors and the very latest in terms of ASP.NET-based development tools. Our ultimate goal was to make our web site serve as a powerful business tool, while ensuring an affordable and immediately meaningful infrastructure.
Our old web site was high on design, but low on practicality. The overzealous use of Flash technology, particularly in site navigation, had made the site complex and cumbersome to update. What is more, site visitors complained they could not find the information they wanted on the mostly static, brochure-ware web site.
XML Tutorial: In the XML Zone you will learn about XML and how to make use of it in your applications.To read and understand this a basic understanding of HTML would be useful. To understand the code provided, you should know VB or ASP.
Get the source code files .XML is used to create many other markup languages. One of the best known is XSL. XSL is made out of XML. The relationship between XML and XSL is very important. If XML is the raw data, XSL is used to change that raw data into a usable format of data.
For example XSL may be used to put color into the XML, or to change the XML into something else.
The development of the XML standard is guided by the W3C.
XML Primer: This document is an introduction to XML targeted to a "hardy user"; an experienced web user or developer. It is the document I would have used to learn XML myself. Prerequisites are a good working knowledge of HTML and WWW transfer protocols, an understanding of the basic concepts of SGML, and some familiarity with standards documents produced by the W3 Consortium.
XML is a couple of years old. There is a wealth of information published about it already. Much of that material is published on the World Wide Web. There is no reason for me to duplicate the information that has already been posted to the web. This document will be a heavily threaded road map to other documents that already exist.
