I would suggest to take the new XML exam 142 which will be releasted after 20 days( I was in a hurry, couldnt wait). I do not know the material for the new exam, but for current 141 exam, following are some useful resources:
1. O'reily XSLT book. 2.XML In a nutshell 3.Professional XML 2nd edition. 4.Whizlab exam simulator
Also I found a xml editor(more than a editor), xml cooktop which is very very helpful in learning XPATH and XSLT. You can write XPATH location paths against xml document and see the result with out writing any code. Same for XSLT. there website is XML Cooktop
