Return

Element — the parentElement node

getPublicId()

Gets the public ID of the external subset data for theDocumentType node.

Return

String — the public ID of the external subset data

Gets the system ID of the external subset data for theDocumentType node.

Return

String — the system ID of the external subset data

getValue()

Gets the text value of all nodes that are direct or indirect children of the node, in the orderthey appear in the document.

Return

String — the text value of all nodes that are direct or indirect children of the node
