Re: Using Jivan in a Barracuda App

DefaultDOMWriter uses XMLC to format the DOM.  You can create your own 
DOMWriter if you want.  This is actually why I wanted to rename 
DefaultDOMWriter to XMLCDOMWriter.  Calling is "Default" hides its 
implementation too much, and the whole point to switch out implementations 
at will anyway, not use a single default one.  The DOMLoader is the more 
generic of the 3 interfaces.  Anyway, knowing that, you can create your own 
DOMWriter implementation that doesn't use XMLC's DOM formatter.  Oh, and I 
forgot, there still is a dependency on XMLC via the 
XMLCDeferredParsingDOMFactory instance created by default in the 
DefaultDOMLoader.  Hmm....  Those should really be separated more.  Maybe 
we should add another getGlobalInstance() that takes a DOMFactory as a 
parameter and have the default dom factory loaded up via reflection.  That 
way, DefaultDOMLoader would be much more generic.  Anyway...


Here are some ways to use the JivanDOMFactory....

First do...
DefaultDOMLoader loader = DefaultDOMLoader.getGlobalInstance();

Then, either use the object repository assember as shown by Thelmo below 
(except change XMLCDeferredParsingDOMFactory to JivanDOMFactory) or use the 
following...


JivanDOMFactory jfactory = new JivanDOMFactory();
jfactory.setServletContext(getServletContext());
loader.setDefaultDOMFactory(jfactory);

//note that you can also choose to set the default dom factory to something 
else and use Jivan for a specific fully qualified class name (String) or 
file path such as....
String docPath = "/WEB-INF/mydocs/myfile.html";
loader.registerDOMFactory(jfactory, docPath);


Then do....

Document doc = loader.getDOM(docPath);


Of course, you can skip the DOMLoader as you did before, but at that point, 
you might as well just load things as described here...
http://www.jivan.org/parser/samples.html

You can also look at how JivanDOMFactory is implemented to for an example 
of how to use it directly.

Hope that clears things up a bit.
