Comment

public interface Comment
implements CharacterData

org.w3c.dom.Comment

This interface inherits from CharacterData and represents the content of a comment, i.e., all the characters between the starting ' '. Note that this is the definition of a comment in XML, and, in practice, HTML, although some HTML tools may implement the full SGML comment structure.

No lexical check is done on the content of a comment and it is therefore possible to have the character sequence "--" (double-hyphen) in the content, which is illegal in a comment per section 2.5 of [XML 1.0]. The presence of this character sequence must generate a fatal error during serialization.

`abstract boolean`	`hasChildNodes()` Returns whether this node has any children.
`abstract Node`	`insertBefore(Node newChild, Node refChild)` Inserts the node `newChild` before the existing child node `refChild`.
`abstract boolean`	`isDefaultNamespace(String namespaceURI)` This method checks if the specified `namespaceURI` is the default namespace or not.
