Implementation Dependancy of DOM and SAX

[Aji Ozkan]

Hi
Does any one here knows the meaning of "Implementation Dependancy of DOM and SAX Parser".
Actually i have to do a comparison of diferent parsers for above topic.Any docs/links regarding implementation dependancy will be of great help.

Typically parsers that build DOM Document objects actually use a SAX parser to scan the input text. Thats why you get a SAXException from a DOM parser parse method.
Does that count as "Implementation Dependency"???

I can't figure out what is there to compare? If you use the JAXP API, there is no dependency to the implementation and that's it.
Of course, anything that is not provided by the standard JAXP API (e.g. schema validation in all but the latest versions of JAXP) is completely implementation-dependent.
Or am I missing something here?

HI Lasse Koskela
I am doing a study of 6 diff XML Parsers(All written in Java).
I need to find out the implementation dependency in thses parsers.
How do i do it?
I hope my question is clear.

Well, if I'd only know what "implementation dependency" means...?
If it means just whether a given parser can be used through the standard JAXP APIs, then the answer should be right there in the parser's documentation. If it's something else, you'll have to define the term to us.

I suppose you could compare the degree of support for various XML standards.
This page at the W3C could get you started on the various standards.
