DOM or SAX for a kind of job and relevant library

[eluser]veledrom[/eluser]
Hi,

I have a remote XML file (size between 10KB-10MB) and want to read it with either DOM or SAX. I know that DOM uses plenty of memory by storing whole content, SAX don't.

Since file is stored on remote source, I'll have to access it over http, what would be your suggesting?

Is there any CI library to handle this type of job?

Thanks
