The syntax rules of XML are very simple and logical. The rules are easy to learn, and easy to use.
XML Documents Must Have a Root Element
XML documents must contain one root element that is the parent of all other elements:
<root> <child> <subchild>.....</subchild> </child> </root>
In this example <note> is the root element:
<?xml version="1.0" encoding="UTF-8"?> <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>
