<h1 class="topictitle1">Using XML</h1>
|
||
|
|
<div><p>This topic explains what XML is, what extensions and companion
|
||
|
|
standards it uses, and what it can do for you.</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) that functions as the standard way to describe your
|
||
|
|
information. Using XML to share standardized information 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 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.</p>
|
||
|
|
<p>For example, you might want to create an efficient way to share information
|
||
|
|
(for example, 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, 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>
