I also think Lucene is overkill, assuming that you don't need to persist the XML you're talking about. Why not just use Java Sets? See http://java.sun.com/docs/books/tutorial/collections/interfaces/set.html for how to do set intersection, union, difference, etc.
And what's the difference between matching ids from both xml and duplicate ids from both xml? Erick On 12/4/06, Eshwaramoorthy Babu <[EMAIL PROTECTED]> wrote:
Hi Buics, Thanks for your response.. I will receive 2 xml files, I have to compare these 2 and generate a xml report with below 1. Matching id's from both xml 2. Duplicate id's from both xml The requirement is for reconcilation of 2 application data. For this I have to get the get all id's from 1st xml and search for the matching and duplicate in the 2nd xml. If I use database again I have to write procedute/JAVA to do the comparison and generate the report.
