Thanks a lot Bob for your inputs. Here is the sample structure of how the
xml
<dataset>
<user>
<userid>1001</userid>
<firstname>XXXX</firstname>
</user>
<user>
<userid>1002</userid>
<firstname>XXXX</firstname>
</user>
<user>
<userid>1003</userid>
<firstname>XXXX</firstname>
</user>
<useraddress>
<userid>1001</userid>
<street>XXXX</street>
<city>XXXX</city>
<country>XXXX</country>
</useraddress>
<useraddress>
<userid>1002</userid>
<street>XXXX</street>
<city>XXXX</city>
<country>XXXX</country>
</useraddress>
<useraddress>
<userid>1003</userid>
<street>XXXX</street>
<city>XXXX</city>
<country>XXXX</country>
</useraddress>
</dataset>
I was looking at getting all the details of user id 1001 and process it and
then continue with userid 1002. Is this kind of operation possible with jibx
?
Thanks
Madhu
