Hi Sairam,
I made the W3Schools XML exam, and it was so easy for me, also I worked in a small project using JSP, XML, and XSLT, and I made the design of a report genaeration software for the same project using JSP, XML, XSLT, and SVG.
I'm preparing now for the XML exam too, although I know XML, I find it not easy to study for the IBM exam, it needs a lot time and a lot of studying, the main problem is that you have to get information from many resources, there is no one book that can give you all you need for the exam (like
java exams), I would do the SCWCD exam first, but the only thing that made me choose the XML exam is that there will be a new version of the SCWCD soon, and I will do both of them, so I decided use the time till the new vrsion of SCWCD is there in studying for XML exam.
GOOD LUCK
