[WIKI-UPDATE] SAX Fri Feb 21 15:00:03 2003
Page: http://wiki.cocoondev.org/Wiki.jsp?page=SAX , version: 13 on Fri Feb 21 13:13:53 2003 by SylvainWallez
- Some people thought "That's inconvenient! Why can't we handle the document in a sequential manner instead?". So they invented (particulary a guy named David Meggison invented) SAX, the __S__imple (or "Streaming") __A__pi (for) __X__mldocuments.

- The pipeline starts with a Generator that knows how to read __something__ (for example an XML document) and from that generate a stream of SAX events ("document begins" etc). Then there might be a bunch of other components that modifies the stream of SAX events, for instance using XSLT or some other transforming algorithm.

- In the end there is the Serializer that listens to the SAXEvents and translates them to normal text.
+ In the end there is the Serializer that listens to the SAX events and translates them to a binary data stream. This transformation to binary data can be as simple as "translating" SAX events to text (the usual form of an XML document), or as complex as producing PDF from XSL:FO or a JPEG image from SVG.
- When the XMLGenerator looks at an XML file and sees "<doc>" it fires the SAXEvent "element 'doc' begins".

- A Transformer might take it from here, perhaps instructed to transform every "<doc>" element into a "<document>" element. So when this Transformer recieves the "element 'doc' begins", it fires the SAXEvent "element 'document' begins".
