Q:

SGML parser in Java?

I'm looking for a parser in Java that can parse a document formatted in SGML.
For duplicate monitors:
I'm aware of the two other threads that discuss this topic:
Parsing Java String with SGML
Java SGML to XML conversion?
But neither has a resolution, hence the new topic.
For people that confuse XML with SGML:
Please read this: http://www.w3.org/TR/NOTE-sgml-xml-971215#null
(in short, there are enough subtle differences to at least make it unusable in it's vanilla form)
For people who are fond of asking posters to Google it:
I already did and the closest I could come up with was the widely popular SAXParser: http://download.oracle.com/javase/1.4.2/docs/api/javax/xml/parsers/SAXParser.html
But that of course is meant to be an XML parser. I'm looking around to see if anyone has implemented a modification of the SAX Parser to accommodate SGML.
Lastly, I cannot use SX as I'm looking for a Java solution.
Thanks! :)

A:

I have a few approaches to this problem
The first is what you did -- check to see if the sgml document is close enough to XML for the standard SAX parser to work.  
The second is to do the same with HTML parsers. The trick here is to find one that doesn't ignore non-HTML elements.
I did find some Java SGML parsers, more in acedemia, when searching for "sgml parser Java".  I do not know how well they work.
The last step is to take a standard (non Java) SGML parser and transform the documents into something you can read in Java. 
It looks like you were able to work with the first step.
