I am working towards my XML Certification as well. Here is some information to overflow your 'input stack'. Links: http://javaranch.com/gramps/XMLLinks.jsp (Tons of links) Books: If memory serves me, Ajith used "XML Bible" to study for the exam. In addition he recommended reading the DOM spec from http://www.w3.org/DOM/ Additionally why not check out this week's give away book, "Professional Java XML". Ajith rated it 10/10 as 'The most comprehensive XML guide I have ever read'. I am unaware of any specific 'Study guide for the IBM XML Certification exam' type book. Maybe someone can write one... Hope this helps. Glen Jansen Java/XML Cert in Training.
