What does XML look like?
Let’s look at some examples of XML text:
<?xml version="1.0" encoding="ISO-8859-1"?>
<letter>
<to>Buddy</to>
<from>Fran</from>
<greeting>Howdy!</greeting>
<body>Don't forget me this weekend!</body>
</letter>
The first line in the document - the XML declaration - defines the XML version and the character encoding used in the document. In this case, the document conforms to the 1.0 specification of XML and uses the ISO-8859-1 (Latin-1/West European) character set. Note that there is no closing tag for this declaration. Unlike most elements of an XML document, the declaration does not require a closing tag.
The next line describes the root element of the document (as if it were saying,"this document is a letter"). Note that this element has a closing tag.
The next four lines describe four child elements of the root (to, from, greeting,
and body). Note that all of these elements also have closing tags.
