The 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 a Document, the
Document interface also contains the factory methods needed
to create these objects. The Node objects created have a
ownerDocument attribute which associates them with the
Document within whose context they were created.

| Method Detail |
public DocumentType getDoctype()
DocumentType) associated
with this document. For HTML documents as well as XML documents without
a document type declaration this returns null. The DOM Level
1 does not support editing the Document Type Declaration, therefore
docType cannot be altered in any way.public DOMImplementation getImplementation()
DOMImplementation object that handles this document. A
DOM application may use objects from multiple implementations.public Element getDocumentElement()
public Element createElement(java.lang.String tagName)
throws DOMException
tagName - The name of the element type to instantiate. For XML, this
is case-sensitive. For HTML, the tagName parameter may
be provided in any case, but it must be mapped to the canonical
uppercase form by the DOM implementation.Element object.public DocumentFragment createDocumentFragment()
DocumentFragment object.DocumentFragment.public Text createTextNode(java.lang.String data)
Text node given the specified string.data - The data for the node.Text object.public Comment createComment(java.lang.String data)
Comment node given the specified string.data - The data for the node.Comment object.
public CDATASection createCDATASection(java.lang.String data)
throws DOMException
CDATASection node whose value is the specified
string.data - The data for the CDATASection contents.CDATASection object.
public ProcessingInstruction createProcessingInstruction(java.lang.String target,
java.lang.String data)
throws DOMException
ProcessingInstruction node given the specified
name and data strings.target - The target part of the processing instruction.data - The data for the node.ProcessingInstruction object.
public Attr createAttribute(java.lang.String name)
throws DOMException
Attr of the given name. Note that the
Attr instance can then be set on an Element
using the setAttribute method.name - The name of the attribute.Attr object.
public EntityReference createEntityReference(java.lang.String name)
throws DOMException
name - The name of the entity to reference.EntityReference object.public NodeList getElementsByTagName(java.lang.String tagname)
NodeList of all the Elements with a
given tag name in the order in which they would be encountered in a
preorder traversal of the Document tree.tagname - The name of the tag to match on. The special value "*"
matches all tags.NodeList object containing all the matched
Elements.
