Thats a classic trade-off of resource-usage/performance vs convenience.
If you find DOM to be a more convenient API to use than SAX, you might
want to consider persistent DOM implementations that provide a caching
mechanisms for managing resource usage while providing a DOM interface
for manipulating the document. Ipedo (www.ipedo.com)  implements one, as
does Infonyte http://www.infonyte.com/en/index.html
<http://xml.darmstadt.gmd.de/xql/index.html> . There might also be some
open source implementations.

	Dear friends,
	
	Many thanks for your help. Now, I know I can manage large XML
files with SAX
	and it works fine. The problem now exists when I need to update
the content
	of an element or any of its attributes. I'm not sure, but I
think that SAX
	cannot be used for that purpose.
	
	Can you confirm me this topic?
	Which is the best way to fix this problem?
	
	Thanks again and best regards,
	M.A.
