Wednesday, August 22nd, 2007CHAPTER 4 CLIENT-SIDE XML 103 Figure 4-3. Working with XML content in Flash Now that you understand the ways in which you can work with XML on the client, it s time to look at XML support in the most common web browsers. Examining XML Support in Major Browsers XML support can include the display of raw XML and conformity with The W3C DOM XML Schema Definition (XSD) Language XSLT Before discussing browser support, let s have a quick refresher about these concepts and look at some pertinent points. Understanding the W3C DOM A DOM represents a document as a series of related objects. The HTML DOM provides an application programming interface (API) for addressing parts of a web document. If you ve worked with JavaScript, you may have used the HTML DOM to access specific elements within an XHTML document. For example, you can find the title of an XHTML document with document.title or count the number of images on a page using document.images.length. If you ve created DHTML, you ve addressed the issue of browser incompatibility. The W3C has released a recommendation that provides for three different levels of DOM support, numbered 1 to 3, respectively. The higher the DOM level, the larger the feature set that is supported. The W3C refers to the early Netscape Navigator 3 and Microsoft Internet Explorer (IE) 3 DOMs as Level 0. You can find out more at http://www.w3.org/DOM/. DOM is also separated into different sections: Core, XML, and HTML. The HTML DOM extends some of the Core functionality. Because it extends this functionality, it s compatible with earlier DOM implementations.
