XML elements

• An element is a unit of XML data that begins with a start tag and ends with an end tag.
• The start tag provides the name of the element and contains any attributes assigned to the element.
• The end tag repeats the element name, prefixed with a slash (/).
• The text between an element's start and end tags is called the element's content.
• Elements can contain other elements:
• A child element is one that's contained within another element.
• The element that contains a child element is known as the child's parent element.
• The highest-level parent element is known as the root element.
• Child elements can repeat within a parent element, but an XML document can have only one root element.
