about SAX and DOM parsers

[Eric Delacroix <ed...@hotmail.com>]

hello,

I tried to understand why there is SAX and DOM functions implemented in 
batik, and in which cases they were used.
So is SAX used only to build the GVT tree? and then, we have a mirror of the 
DOM in Java objects, so the methods used are the DOM ones?
And in consequence, which parser is used in which case between crimson and 
xerces? And eventually, why? I know it's quite abstract as a question, but I 
think it could be helpful to fully understand the way all this works...
Thank you for helping.

Re: about SAX and DOM parsers

Hello Eric,

Batik uses the org.apache.batik.util.XMLResourceDescriptor class to 
define which SAX Parser to use (Crimson or Xerces or any other 
implementation). Then, we build a DOM tree using our own DOM 
implementation which is needed to support the SVG DOM features. The DOM 
tree is then bound to a GVT tree (org.apache.batik.gvt) thanks to the 
bridge module (org.apache.batik.bridge).

You can refer to the web site documentation:
http://xml.apache.org/batik/architecture.html
