![]() The DOM by distinguishing it from other systems that may seem to be This section is designed to give a more precise understanding of May be manipulated, and they are part of the object model. Theįunctions associated with these objects determine how the objects Languages, the data itself is encapsulated in objects that hide theĭata, protecting it from direct external manipulation. Represented by an abstract data model, not byĪn object model. The structure of SGML documents has traditionally been the relationships and collaborations among these interfaces and.the semantics of these interfaces and objects - including both. ![]() ![]() the interfaces and objects used to represent and manipulate a.In other words, the nodes in the aboveĭiagram do not represent a data structure, they represent objects, Using objects, and the model encompasses not only the structure ofĪ document, but also the behavior of a document and the objects of The traditional object oriented design sense: documents are modeled The name "Document Object Model" was chosen because it is an " object model" in For instance, the DOM may notĬontain whitespaces in element content if the parser discards Note: There may be some variations depending on the Structure model, in accordance with the XML Information Set. Representation of the same document, they will create the same Two Document Object Model implementations are used to create a Of DOM structure models is structural isomorphism: if any Methods (this does not include attributes). Information items which can be reached by using "tree-walking" The term "tree" when referring to the arrangement of those This specification, we use the term structure model toĭescribe the tree-like representation of a document. Logical model that may be implemented in any convenient manner. The relationships among objects be implemented. Implemented as a tree or a grove, nor does it specify how The DOM does not specify that documents must be Serves as the root of the element tree for the document. Or more comments or processing instructions the root element Each documentĬontains zero or one doctype nodes, one root element node, and zero "grove", which can contain more than one tree. Much like a tree to be more precise, which is like a "forest" or In the DOM, documents have a logical structure which is very Graphical representation of the DOM of the example table Require the object binding runtimes generally associated with such ![]() Model can be implemented in any computing environment, and does not In general, IDLs areĭesigned for specific computing environments. Implementation-neutral way to specify interfaces. Note: OMG IDL is used only as a language-independent and Industry-standard scripting language based on JavaScript Specification, we provide language bindings Management Group (OMG) IDL, as defined in the CORBAĢ.3.1 specification. Interfaces, we have chosen to define the specifications in Object To provide a precise, language-independent specification of the DOM TheĭOM is designed to be used with any programming language. Object Model is to provide a standard programming interface thatĬan be used in a wide variety of environments and applications. XML internal and external subsets have not yet been specified.Īs a W3C specification, one important objective for the Document Anything found in an HTML or XML document can be accessed,Ĭhanged, deleted, or added using the Document Object Model, with aįew exceptions - in particular, the DOM interfaces for the Navigate their structure, and add, modify, or delete elements andĬontent. With the Document Object Model, programmers can build documents, Nevertheless, XML presents this data asĭocuments, and the DOM may be used to manage this data. Systems, and much of this would traditionally be seen as data Increasingly, XML is being used as a way of representing manyĭifferent kinds of information that may be stored in diverse Specification, the term "document" is used in the broad sense. Way a document is accessed and manipulated. It defines the logical structure of documents and the The Document Object Model (DOM) is an application programmingĭocuments.
