Hi Mallika,
No single book covers all the topics mentioned in the objectives. You need to go through some online resources also apart from reading books.
You can buy "XML in a Nutshell" and "Professional XML" which should cover most of the topics. I don't think XSLT cook book is required.
Also, go thru IBM's developerWorks site for articles on security etc.
Go through other resources mentioned in javaranch's faq
