This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hi Madhav, First I would suggest you to look at XQEngine, a full java API. The problem lies in its API factor: there is no GUI available. So, you'll have to write some amount of code before you can actually try your queries. You may also try DataDirect jXTransformer. This more elaborate API allow you to perform XML Queries on any relational database. They have an evaluation version that you can download from their website. There is also the Micro$oft XML Query Language Demo that provides you with an online query facility. Cheers
