I know a little bit about XML. I just passed SCPJP with 91%. I wanted to go next certification. XML may be one choice for me. I wanted to switch my next career to Web staff even though I am working with 3 tier Client/Server application,like Tuxedo, VB. I dont have any working experience with XML and Java. Can someone tell me some info like, what is advantage for taking XML, how hard is it, where am I starting, such,... thanks in advance!
