Ok, after fighting through some late problems, it looks like I've gotten through the first iteration. I'm posting to the dev list first because it probably isn't ready for public consumption.
Here is a link where you can grab JSDigester v.1, the client-side Javascript-based implementation of Commons Digester... http://www.omnytex.com/jsdigester.zip Just unzip it and load up viewme.html. It creates a relatively simple object graph using four rules: ObjectCreateRule, SetPropertiesRule, BeanPropertySetterRule and SetNextRule (that last one was a bit of a pain!). Other rules can be added later. I've tried to comment the heck out of it, so I don't think anyone will have much trouble understanding it. Here's a quick explanation of the files included... viewme.html is just a test/sample usage page. All the action takes place in the doit() function, so that's what you'll be interested in. jsdigester.js obviously contains all the JSDigester code itself, including the four rules. logging.js is a quick logging implementation I threw together to help with this. It should look a bit like JCL. There are two implementations, one that logs messages to alert() popups, another that writes to an element on the page (usually a <div>) named DivLogOut. That's the one that is used here. sax.js is the simple SAX parser from Mozillas' JSLib extension library. I'm reasonably sure the MPL is compatible with the ASF, but if there is any interest in moving this into the ASF we'll obviosly need an answer from someone who knows what they are talking about :) mytypes.js are the "classes" that make up the sample object graph. Should be rather self-explanatory. I've tried not to veer too far from the real Digester in terms of how it works, so it should look very familiar externally. Internally though, I only glanced at the real Digester code a handful of times, otherwise it is a fairly "clean-room" implementation (many things wouldn't make sense in Javascript anyway, so there was little point in trying to duplicate the code verbatim). At this point, I'm interested in any comments. Is this worth anything to anyone (besides me)? Anyone have thoughts on what the next step(s) should be (if any)? Thanks all! -- Frank W.
