promote
XML technologies?

Understanding XML

XML (eXtensible Markup Language) allows for the description and organization of information in a way that is easily understandable by both humans and computers.
You can better share this information and its description with others via the Internet, a network, or any other means.
You can use XML to create your own markup language with rules and tags describing your data and products.
These rules and tags are generally described in a document called a DTD (Document Type Definition) or an XML schema file.

The utility of XML

XML is therefore the ideal format if you want to create a way to easily share information with your partners and suppliers, or to communicate with machines (printers, measuring devices, computer interfaces, etc.).
Furthermore, DTDs and XML schemas define the standard for your electronic exchanges: in addition to using the same language, you define the same communication rules.

HTML vs XML: what are the differences?

XML and HTML both use tags, but here are the differences:

HTML

A presentation language
Used to display content (headings, paragraphs, images, etc.)
Tags are predefined

				
					<h1>Titre</h1>
<p>Bonjour</p>

HTML says: “how to display”

XML

A data description language
Used to store and transport information
Tags are customizable

				
					<personne>
  <nom>Alice</nom>
  <age>25</age>
</personne>

XML says: “what the data is”

What are the advantages of XML?

Where is XML found and what is it used for?

eBusiness Applications

XML facilitates the use of Electronic Data Interchange (EDI) for information exchange and transactions between businesses and consumers.

General Applications

XML is a standard method of data storage that makes it easier for applications and devices of all kinds to use, store, send, and display data.

Mobile Computing

XML provides portable and structured information types for display on ubiquitous (wireless) computing devices such as smartphones, embedded systems, and other peripherals. For example, WML (Wireless Markup Language) and VoiceXML describe the visual and voice interfaces of wireless devices.

Web Publishing

XML allows you to create interactive pages, enables third parties to modify these pages, and facilitates the creation of e-commerce applications. Different forms of rendering are possible to match various devices by combining a stylesheet for formatting and an XSL/XSLT transformation processor.

Web Search and Web Task Automation

Because XML defines the type of information within a document, search engines can index it more easily to provide better results for web search queries: For example, if you search for "Paris Hilton," you will find instances of the term "Paris" outside the original context. If you want the information contained within the tag to be returned, you must use the correct context.

Metadata Applications

XML facilitates the expression of metadata in a portable and reusable format.

Standards and extensions around XML

Other XML standards and extensions work together to make your information more mobile and useful.

Read our mini-guide: “Why are standards in document engineering so important?”

In addition to XML, 4D CONCEPT implements:

APIs

Application Programming Interfaces (APIs) leverage XML information using a standard set of portable interfaces and commands, for example:

DOM, which allows for accessing, manipulating, and creating data as programming objects with methods and events. DOM is suitable for cases where you want to analyze a few XML documents but with a high degree of control over their content.

SAX, which is the ideal API for processing numerous or large documents. This API allows for obtaining information from XML documents but does not allow for adding or modifying data within them.

X-Languages

XSL and XSLT work together to allow you to display XML data in multiple ways, such as on a browser, a smartphone, or in a printed brochure.

XLink allows you to connect your XML document to other resources on the Web (files of all types, database results, etc.).

XPath and XPointer are languages that allow for searching and finding data within the hierarchical structure of an XML document.

XML Schema

The XML Schema Language defines the logical structure of an XML document and offers more possibilities than a DTD: enumeration of minimum and maximum allowed elements, constraints on values, additional data types and inherited data type definitions, easier data import and export, etc.

NAMESPACES

NAMESPACES are pointers that help you distinguish between different XML elements or attribute names; this is useful when using an XSLT stylesheet or multiple DTDs to avoid duplicates and confusion between identical terms.
