Dom2 Analysis In Embedded Systems

Recently, with the rapid development of the software and hardware technology, the mobile devices, especially the mobile phones, have had the ability to access internet. The browser, which is the most important tool for accessing internet, has been also developed in such devices.However, compared with desktop browser, the browser in embedded device is very simple. For instance, it couldn't run Java Script, doesn't support dynamic web page, and the AJAX technology is not supported also. The browser couldn't fully use various applications which are provided by the internet. The key point to support those technologies is that the browser should implement DOM first.DOM is short for Document Object Model. It is a specification which was distributed by W3C organization on Oct 1st, 1998. The purpose of the specification is to build a platform neutral and language neutral standard interface, which allows the program and the script to access and manipulate the contents, structures and style of the document. The document mentioned here mainly refers to XML and HTML files, other document types which inherit from the two documents are included also, for instance, XHTML files.DOM has already been a standard module in the desktop browsers, but there are little embedded browsers that support DOM. This thesis studied what the DOM is and how to implement the DOM in embedded browser. The main targets of the study are:1. Analyzing the structure and the features of DOM in detail, studying what the DOM is, and what role it acts in browsers.2.Implementing an embedded version of DOM, whose name is miniDOM, in an embedded browser.3.Reducing the memory consumption of miniDOM by using memory swap and resource pool technologies.
