The CommentNode class extends AbstractNode and represents a comment in an HTML or XML document. It holds the comment text that appears between <!-- and --> in the markup. Like TextNode, CommentNode is a leaf node in the DOM tree and does not contain other child nodes.
As a subclass of AbstractNode, CommentNode inherits methods for DOM manipulation, but it is specifically designed for handling comments. It allows for retrieving, modifying, or removing comment content in the document. CommentNode is primarily used to represent and manipulate comment data within the DOM structure.
By inheriting from AbstractNode, CommentNode integrates seamlessly into the broader document structure while providing functionality specific to comment nodes.
