HTML DOM - PART II


HTML DOM
The Document Object Model (DOM) is a platform- and language-independent standard object model for representing HTML or XMLand related formats.
A web browser is not obliged to use DOM in order to render anHTML document. However, the DOM is required by JavaScriptscripts that wish to inspect or modify a web page dynamically. In other words, the Document Object Model is the way JavaScript sees its containing HTML page and browser state.
Because the DOM supports navigation in any direction and allows for arbitrary modifications, an implementation must at least buffer the document that has been read so far.
Hence the DOM is likely to be best suited for applications where the document must be accessed repeatedly or out of sequence order. If the application is strictly sequential and one-pass, the SAX model is likely to be faster and use less memory.
In addition, non-extractive XML parsing models, such as VTD-XML, provide a new memory-efficient option.
