Now I want to compare these 2 files...
if for example the table 't_fpaa_activity''s fields 'clnt_id_n' and 'ssn_n' are matching with my.xml...
Now what I need is their's corresponding values...
15180,236-64-6709
15180,236-64-6666 (2 separate records) in my output...
Can anyone help me in this regard
Thanks in advance

Hi,
There is a visual tool for comparison XML documents.
ExamXML at URL

Hello..
Thanks for replying. But I need to use java for this. I used 2 separate classes to read each of these xml's and stored in a hash table, with table name as key and vector of fields as value for 'dsg.xml'. And for 'my.xml'.....row as key and vector of col as value. And traversed the second vector for each element of the first vector and stored the matching position in a variable. And again traversed the second vector and tried to get the element at the position stored in a variable. Now my problem is printing them as single record.....ie.,
I need somewhat like this...
INSERT into table1 VALUES(...record of first row which matches with the second xml)
INSERT into table2 VALUES(...record of second row which matches with the first xml)
Thanx
