Hi, I have to manage xml's and Strings in my app.

by efficenty and memory saving, is collection(ArrayList) will be much more 'expensive' then array of Strings?

another issue is: i could use the content as regular String, or XML.. is working with XML also makes it more 'expensive' ?

when i say i expensive i talk about taking system sources.

please tell me by any of your exprience if the diffrences are significant?

thanks,

ray.
