As robert mentioned you dont have to know java .. But professional XML, teh prescribed book for the exam has got all the examples written in Java !! So I think tahts what Dhiren ment by saying that u need to know Java to learn SAX and DOM !!! Right Dhiren ?
And if you are already a programmer, just go through teh examples in Java and you can easily see whats going on !!! You dont have to really write code to understand the implementation (of course ..writting code makes you understand it better!! )
