Android: How to parse this kind of XML

Hi and thanks for your help.
I have an XML like this:
http://www.nation.co.ke/news.xml/
And I need to parse in order to extract, for each item, the value of:
<title>
<description>
<articleDate>
<story>
<author>
<photo>
<caption>
I am trying with DOM, but I am a lost because each node
<item>
of the root
<channel>
has 3 children:
<article>
<media>
<link>
Please any help very much appreciated !!!
