DTMNodeProxy

public class DTMNodeProxy extends Object implements Comment, Node, Element, Text, Document, Attr, ProcessingInstruction, DocumentFragment
DTMNodeProxy presents a DOM Node API front-end to the DTM model.

It does _not_ attempt to address the "node identity" question; no effort is made to prevent the creation of multiple proxies referring to a single DTM node. Users can create a mechanism for managing this, or relinquish the use of "==" and use the .sameNodeAs() mechanism, which is under consideration for future versions of the DOM.

DTMNodeProxy may be subclassed further to present specific DOM node types.

How will this be affected by resolution of relative namespace URIs issue?It's not.Should this only be on Document, Element, ProcessingInstruction, Entity, and Notation nodes, according to the infoset? If not, what is it equal to on other nodes? Null? An empty string? I think it should be the parent's.No.Should this be read-only and computed or and actual read-write attribute?Read-only and computed (F2F 19 Jun 2000 and teleconference 30 May 2001).If the base HTML element is not yet attached to a document, does the insert change the Document.baseURI?

public booleanisEqualNode(org.w3c.dom.Node arg)
Tests whether two nodes are equal.
This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode. All nodes that are the same will also be equal, though the reverse may not be true.
Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue , baseURI. This is: they are both null, or they have the same length and are character for character identical. The attributes NamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The childNodes NodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. This is true for Attr nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
For two DocumentType nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: publicId, systemId, internalSubset.The entities NamedNodeMaps are equal.The notations NamedNodeMaps are equal.
On the other hand, the following do not affect equality: the ownerDocument attribute, the specified attribute for Attr nodes, the isWhitespaceInElementContent attribute for Text nodes, as well as any user data or event listeners registered on the nodes.

param
arg The node to compare equality with.
param
deep If true, recursively compare the subtrees; if false, compare only the nodes themselves (and its attributes, if it is an Element).

If the nodes, and possibly subtrees are equal, true otherwise false.

public voidsetStrictErrorChecking(boolean strictErrorChecking)

EXPERIMENTAL! Based on the Document Object Model (DOM) Level 3 Core Working Draft of 5 June 2001..

An attribute specifying whether errors checking is enforced or not. When set to false, the implementation is free to not test every possible error case normally defined on DOM operations, and not raise any DOMException. In case of error, the behavior is undefined. This attribute is true by defaults.

public voidsetTextContent(java.lang.String textContent)
This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single Text node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
The string returned is made of the text content of this node depending on its type, as defined below:
Node type Content
ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null

exception
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
exception
DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

public final booleansupports(java.lang.String feature, java.lang.String version)
Ask whether we support a given DOM feature. In fact, we do not _fully_ support any DOM feature -- we're a read-only subset -- so arguably we should always return false. Or we could say that we support DOM Core Level 2 but all nodes are read-only. Unclear which answer is least misleading. NON-DOM method. This was present in early drafts of DOM Level 2, but was renamed isSupported. It's present here only because it's cheap, harmless, and might help some poor fool who is still trying to use an early Working Draft of the DOM.
