ios/xcode best way for parsing and tableview display

[dracat]

Im new to Xcode/Objective C, I need to create a simple app for displaying some datas from an external xml,My xml looks like:\[code\]<?xml version="1.0"?><news> <article id="1"> <title>Article 1 Title</title> <description>Long description.</description> </article> <article id="2"> <title>Article 2 Title</title> <description>Long description.</description> </article></news>\[/code\]All what I need is to use a xml parser to download and parse this external file, and to display article titles in table view, then when a user click on a title to open a new view and to display that title and description of a selected article,the xml will be updated 1time every 24 hours, so whats the best way for doin this, which xml parser to use (Im newbie to this),Thanks.
