The difference to SAX becomes obvious in the DOM implementation of our example. [PDF]

SAX parses a document sequentially, doing a callback for each thing that it encounters in the XML file. Because this is very fast and takes a minimum amount of memory, it is ideal for some tasks.

SAX parsers use a callback mechanism to parse XML. Applications register a ContentHandler to receive the parsing events. Although this is a little more complicated, it's more efficient because there's no need to build any data structures.

The SAX interface. Subsections: A simple example; Monitoring the sequence of events:

Extensible Markup Language (XML) is everywhere, and many developers are enhancing their apps with XML functionality. The one problem in doing so, though, is that your VB projects become dependent on an external XML parser, be it from Microsoft or a third-party company.

In working on the Smalltalk SAX 2 implementation has generated some questions and issues on which I could use some input. You may find it useful to look at the SAX 2 API. The SAX 2 web site is at: http://www.megginson.com/SAX/SAX2/

Following Soliton's announcement to unleash their APL into the Linux community I decided to review the differences between SHARP APL and APL2 style APLs (IBM's APL2, Dyalog, APL+Win). I have divided the report into several articles, each with a different topic.

A SAX parser example with a simple calculation.

SAX uses the Observer design pattern to tell client applications what’s in a document.[1] Java developers are most familiar with this pattern from the event architecture of the AWT and Swing. In that context, the client programmer implements an interface such as MouseListener that receives events through well-known methods.

Parsing is the process of reading an XML document and reporting its content to a client application while checking the document for well-formedness. SAX represents parsers as instances of the XMLReader interface.

This section contains some SAX examples.

You may find that your XML documents and their various grammars take on a vernacular of their own. As this vernacular finds its way into your documents, you might need to describe it in an abstract and reusable way. One solution is to use custom XML entities to represent common, reusable XML components.

The sax.pl provides a simple API for XML. It includes a set of functions for constructing a XML document. The use of sax.pl requires you to include the line below in your Perl script.

Developers using SAX, for example, will state in their Java source code that the application implements one or more SAX interfaces. [PDF]

The features we've covered so far are probably enough for 90% of SAX applications. But it's useful to know something of the rest of the features, for those occasions when they are needed. This section of the chapter gives a survey of these features and their intended purpose.

With MSXML 4.0, you can use SAX and DOM interchangeably. For example, a process might pass your application a DOMDocument or an IXMLDOMNode object.

Custom JSP tags. Lets you read and proceed XML files. This approach is similar to XMLTextReader stuff in .NET (actually this taglib uses SAX parser).
