Author XML Documents
This topic provides basic information about XML documents.
What Is an XML Document?
A basic XML document is simply an XML element that can, but might not, include nested XML elements.
For example, the XML <books>
element is a valid XML document:
<books>
<book isbn="0345374827">
<title>Maeve Ascendant</title>
<author>Eva Corets</author>
</book>
</books>
Authoring guidelines
There are some things to remember when constructing a basic XML document.
All elements must have an end tag.
All elements must be cleanly nested (overlapping elements are not allowed).
All attribute values must be enclosed in quotation marks.
Each document must have a unique first element, the root node.
