Now, let's assume that all of the command-line args are file names, and we'll try to parse them one-by-one using the parse method from the XMLReader interface: import To find out about the start and end of the document, the client application implements the start Document and end Document methods: method once (even if there have been errors). Default Handler; public class My SAXApp extends Default Handler Start document Start element: poem Characters: "\n" Start element: title Characters: "Roses are Red" End element: title Characters: "\n" Start element: l Characters: "Roses are red," End element: l Characters: "\n" Start element: l Characters: "Violets are blue;" End element: l Characters: "\n" Start element: l Characters: "Sugar is sweet," End element: l Characters: "\n" Start element: l Characters: "And I love you." End element: l Characters: "\n" End element: poem End document Note that even this short document generates (at least) 25 events: one for the start and end of each of the six elements used (or, if you prefer, one for each start tag and one for each end tag), one of each of the eleven chunks of character data (including whitespace between elements), one for the start of the document, and one for the end.These examples simply print a message to standard output, but your application can contain any arbitrary code in these handlers: most commonly, the code will build some kind of an in-memory tree, produce output, populate a database, or extract information from the XML stream. If the input document did not include the Start document Start element: poem Characters: "\n" Start element: title Characters: "Roses are Red" End element: title Characters: "\n" Start element: l Characters: "Roses are red," End element: l Characters: "\n" Start element: l Characters: "Violets are blue;" End element: l Characters: "\n" Start element: l Characters: "Sugar is sweet," End element: l Characters: "\n" Start element: l Characters: "And I love you." End element: l Characters: "\n" End element: poem End document You will most likely work with both types of documents: ones using XML namespaces, and ones not using them.Because of the event-driven nature of SAX, processing documents is generally far faster than DOM-style parsers, so long as the processing can be done in a start-to-end pass.Many tasks, such as indexing, conversion to other formats, very simple formatting, and the like, can be done that way.While a SAX parser may well be used to construct such a tree initially, SAX provides no help for such processing as a whole.A parser that implements SAX (i.e., a SAX Parser) functions as a stream parser, with an event-driven API.SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM).Where the DOM operates on the document as a whole, i.e.

building the full AST of an XML document for convenience of the user, SAX parsers operate on each piece of the XML document sequentially, issuing parsing events while making single pass A SAX parser only needs to report each parsing event as it happens, and normally discards almost all of that information once reported (it does, however, keep some things, for example a list of all elements that have not been closed yet, in order to catch later errors such as end-tags in the wrong order).

Thus, the minimum memory required for a SAX parser is proportional to the maximum depth of the XML file (i.e., of the XML tree) and the maximum data involved in a single XML event (such as the name and attributes of a single start-tag, or the content of a processing instruction, etc.). A DOM parser, in contrast, has to build a tree representation of the entire document in memory to begin with, thus using memory that increases with the entire document length.

This takes considerable time and space for large documents (memory allocation and data-structure construction take time).

The compensating advantage, of course, is that once loaded any part of the document can be accessed in any order.
