iphone xml handing
<p>I want my app to read a XML via internet. </p>

<p>Also I want to keep the previously download xml so next time I may not need to download again until certain hours is passed or whatever period of time according to settings.</p>

<p>Do you recommend me to download it first and store locally before process it? Or should I process it while downloading (with libxml2 I guess)?</p>

<p>What do you usually with apps using remote XML?</p>

<p>Targeting 3.0 devices btw.</p>
