Parsing XML file in Chunks.

I have parsed the huge XML file using
and loaded the information in my POJO's. I used these POJO and committed data to database.
Now, I have a requirement to parse the huge XML file in Chunks. Meaning, parse partially to a threshold limit and commit to database and then again parse the left out. Can we do this using STAX API.
For example, I have 50K entries and want to set threshold limit for parse for 500. In this case, can i parse 500 entries and store in database and then continue parsing remaining.

SAX or Stax is exactly what you want then. Since the parse only deals with one Node at a time, it takes very little memory.
The down side will be somewhat more complex programming for you.
Beware the trap of thinking that the characters() method grabs a complete text node.
