Create a Simple Filter
The simple filter example demonstrates how SAX can be used to filter content to create a subset of the original document being parsed. In this example, the application parses books.xml and produces a document fragment that contains only <title> elements and characters. The application is kept simple to demonstrate the fundamental principles involved in transforming documents with SAX, including the following:
How to detect the presence of an element in an XML document and how to write the element's content to the application's output.
The essential SAX methods you must use to conditionally process content.
How to set a flag to indicate across events that an element is within scope.
How to create a document fragment.
