Chapter 1 — Introduction to XML and Data Structure
XML documents are composed of elements and attributes. Elements represent the main structure of the data, while attributes provide additional information about those elements. Attributes appear inside the opening tag and usually describe properties or metadata related to the element.
Example: Elements with attributes
<book id="B001">
<title>Learning XML</title>
<author>John Smith</author>
</book>In this example, the id attribute uniquely identifies the book.
