<h1 class="topictitle1">XML introduction</h1>
|
||
|
|
<div><p>Extensible Markup Language (XML) allows you to describe and organize
|
||
|
|
information in ways that are easily understandable by both humans and computers.
|
||
|
|
You can then share that information and its description with others over the
|
||
|
|
Internet, an extranet, network, or in other ways.</p>
|
||
|
|
<p>XML, like Standard Generalized Markup Language (SGML), is a metalanguage.
|
||
|
|
A metalanguage allows you to define a document markup language and its structure.
|
||
|
|
For example, both XML and Hypertext Markup Language (HTML) are derived from
|
||
|
|
SGML.</p>
|
||
|
|
<p>You can use XML to create your own markup language that includes a set
|
||
|
|
of rules and tags that describe information suited to your needs, for example,
|
||
|
|
name, title, address, and zip code. You define this markup language in a document
|
||
|
|
type definition (DTD) or XML Schema file that functions as the standard way
|
||
|
|
to describe your information. Using XML to share standardized information
|
||
|
|
means you are no longer required to write programs to focus on proprietary
|
||
|
|
software or convert and translate different data formats.</p>
|
||
|
|
<p>You and others can use the DTD or XML Schema definition to tag information
|
||
|
|
that you can then use in a variety of ways: printed on an address label, business
|
||
|
|
card, or stationary; displayed in a Web page; or sorted in a list of data
|
||
|
|
with similar attributes. For example, you might want to create an efficient
|
||
|
|
way to share information (such as purchase orders, shipping acknowledgments,
|
||
|
|
order status, and stock status) with your partners and suppliers. You can
|
||
|
|
use XML to share that information by creating and using XML documents that
|
||
|
|
conform to your DTD or XML Schema, in which you specify the standard for the
|
||
|
|
electronic exchange of information.</p>
|
||
|
|
<p>Although both XML and HTML use tags to describe content, they are also
|
||
|
|
very different:</p>
|
||
|
|
<ul><li>HTML describes how to format information for display and is meant for
|
||
|
|
computer-to-human interaction.</li>
|
||
|
|
<li>XML describes what the information is and is meant for computer-to-computer
|
||
|
|
interaction.</li>
|
||
|
|
</ul>
|
||
|
|
<p>There are many other sources of information regarding the advantages and
|
||
|
|
uses of XML that are readily available on the Internet and through commercial
|
||
|
|
publications. For a complete and comprehensive understanding of the capabilities
|
||
|
|
of XML, you should consult these sources.</p>
