SAX Examples

This example presents a small SAX2 reader that outputs the qualified names and the respective namespace URIs of all elements and attributes in an XML file. Additionally the tree structure of the document is displayed.

SAXTree is a small project that shows you how you can load an XML File and show it in a treeview using the SAX Parser of Microsoft.

Here is a trivial example of using SAX, taken from CodeNotes® for XML, by Gregory Brill. This code is available as a zip file containing a BlueJ package. Note that you must either run the program from the command line, or move the hello.xml file into whatever directory your IDE uses as its default directory.

Once we decide how each element should be displayed, it becomes easy to decide what HTML should be put in the different case statements.

The next function endElement() defines the HTML to display when the closing tag is encountered:

The error handling section checks to see if the XML parser is not at the end of the XML file when an error occurs. If there is an error and we're not at the end of the file, then we capture and send the error code and the line where the error occurred to the browser:

In the startElement function we define what HTML is associated with which element. The function startElement is called by the xml_set_element_handler function in the code. The startElement function must have three parameters:

In this section we will read an XML file and display it as an HTML table, using SAX.

The Java API for XML Processing (JAXP) enables applications to parse and transform XML documents using an API that is independent of a particular XML processor implementation. The Simple API for XML (SAX)is available with the Java API for XML Processing (JAXP). Along with the Document Object Model, SAX is one of two common ways to write software that accesses XML data.

This page documents the various Simple API for XML (SAX) samples included with Xerces. Besides being useful programs, they can be used as SAX programming examples to learn how to program using the SAX API.
