DOM with JavaScript
To introduce document manipulation with the XML Document Object Model, we begin with a simple scripting example that uses JavaScript and Microsoft's msxml parser. This example takes an XML document Fig. 8.2 that marks up an article and uses the DOM API to display the document's element names and values. Figure 8.3 lists the JavaScript code that manipulates this XML document and displays its content in an HTML page. Line 15 lt script type text javascript language JavaScript gt Sun Microsystem's...

message, and to send them to the server. The client also has to parse the XML messages received from the server and display them to the user. This messaging system demonstrates how to incorporate XML into all the tiers of a client server interface. It can be expanded to include many more advanced capabilities, but for our purposes, the system we implement provides ample illustration of XML. Because the XmlMessenger uses Sun's Java implementation of the org.w3c.dom package, Chapter 8 is a...

XML provides a way of describing data in a rich, flexible and efficient way by marking up data with descriptive tags. However, XML does not provide a way to locate specific pieces of structured data within a given document. For example, an XML document containing data about books published by Deitel amp Associates, Inc., would need to be parsed and then searched through element by element in order to find a specific book. For large documents, this process could be inefficient and error prone....
