Question

Differentiate between root element and head element

Answer 1

The root node is the root of the tree. A root node does not occur except as the root of the tree. The element node for the document element is a child of the root node. The root node also has as children processing instruction and comment nodes for processing instructions and comments that occur in the prolog and after the end of the document element.

and I'm confused about the root node, document element terminologies, as well as root element that sometimes people use.

Answer 2

The head element consists of the heading of all the elements like scripts, document, and other information.

The root element is a single element in XML document and it contains all the other elements

Explanation:

Root Element

• Every document has single root element in its document file. The single root element contains all the other elements of the document.
• If there is no root element in a file then it would mean that the particular file of XML is 'corrupted'
• The XML document should contain the root element which has the various other 'XML elements'

Head Element

• The head element is the heading part of the document and it contains all the heading elements. These could be the heading of the page, document, script or more.
• The heading element is needed in a document which describes the document and is also referred to as "metadata"
• The head element also contains the different links to other scripts files or documents
