Bulk XML messages

[Uma Reddy]

I need design advice on how to bulk smaller XML messages into one big XML message. Basically, we have XML messages that are getting posted to a JMS Topic. When we have 500 messages in the JMS topic, we want to bulk these 500 messages into one big XML message and make one database call(batch update) instead of 500 calls. What are the best ways of doing this. Also, are there other ideas of achieving the same thing. Thanks in advance.

which parser are you using ? Dom parser , sax parser or another one

Sounds like you want to build the text of a new document with a root that contains all the little documents.

I would certainly treat this as a pure text manipulation problem - exactly how depends on the content of the small messages. Do they start with a declaration like:

<?xml version='1.0' encoding='utf-8'?>

if so you will need to trim that text - having one inside the big document will cause an error.

Thanks for the responses. We are using sax parser
