Most new editions normally tend to have atleast 70 percent of the same content as the old edition. However I do think that it is much better to use the second edition for 141 preparation primarily because it covers the actual stuff needed for the exam and IBM recommends it. I have not compared both the editions completely, but I did find quite a few differences. For example,the second edition covers SAX2 instead of SAX1, has a separate chapter on XPath, UDDI and WSDL (last chapter), ebusiness integration etc. However to answer your question as to whether the first edition is good enough to start preparation for 141, I think the answer is yes. Also there is an enormous amount of material on the web about XML, which should really help for 141 preparation. Also there is atleast one guy, who has posted on this board, who did not even read Professional XML and passed 141. However I think, most people would rather read a single book completely than read bits and pieces from all over the place, since the concepts flow smoothly, if you read a single book. Maybe others can shed more light on the differences between the two editions. Just my two cents ... Shashank
Hi daisy/Shashank, I dont think the 1st edition is suitable for test 141. It's too dated. It covers SAX1.0, XDR Schema - a M$' dialect. Becoz the book is written by many authors, the concepts don't smoothly flow together, and it covers many technologies but fails to extend each. The 2ed might be a good xml book.
