76<a href="http://www.w3.org/TR/REC-xml">XML is a standard</a> for
77markup-based structured documents. Here is <a name="example">an example XML
78document</a>:</p>
79<pre>&lt;?xml version=&quot;1.0&quot;?&gt;
80&lt;EXAMPLE prop1=&quot;gnome is great&quot; prop2=&quot;&amp;amp; linux too&quot;&gt;
81 &lt;head&gt;
82 &lt;title&gt;Welcome to Gnome&lt;/title&gt;
83 &lt;/head&gt;
84 &lt;chapter&gt;
85 &lt;title&gt;The Linux adventure&lt;/title&gt;
86 &lt;p&gt;bla bla bla ...&lt;/p&gt;
87 &lt;image href=&quot;linus.gif&quot;/&gt;
88 &lt;p&gt;...&lt;/p&gt;
89 &lt;/chapter&gt;
90&lt;/EXAMPLE&gt;</pre>
91<p>The first line specifies that it's an XML document and gives useful
92information about its encoding. Then the document is a text format whose
93structure is specified by tags between brackets. <strong>Each tag opened has
94to be closed</strong>. XML is pedantic about this. However, if a tag is empty
95(no content), a single tag can serve as both the opening and closing tag if
96it ends with <code>/&gt;</code> rather than with <code>&gt;</code>. Note
97that, for example, the image tag has no content (just an attribute) and is
98closed by ending the tag with <code>/&gt;</code>.</p>
99<p>XML can be applied sucessfully to a wide range of uses, from long term
100structured document maintenance (where it follows the steps of SGML) to
101simple data encoding mechanisms like configuration file formatting (glade),
102spreadsheets (gnumeric), or even shorter lived documents such as WebDAV where
103it is used to encode remote calls between a client and a server.</p>
