public Element getDocumentElement()
public Element getElementById(java.lang.String elementId)
Element

null

has this ID
. The DOM implementation must have
information that says which attributes are of type ID. Attributes
with the name "ID" are not of type ID unless so defined.
Implementations that do not know whether attributes are of type ID or
not are expected to return null

Document
interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data. Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of aDocument
, theDocument
interface also contains the factory methods needed to create these objects. TheNode
objects created have aownerDocument
attribute which associates them with theDocument
within whose context they were created. See also the Document Object Model (DOM) Level 2 Core Specification.
