		<description><![CDATA[As I&#8217;m currently studying for a BSc in Mathematics with the Open University and I am trying to teach myself Common Lisp, I decided to try and create a function that outputs the Fibonacci nth element. Here it is, I think is a nice example to illustrate how recursion works in Lisp.

		<description><![CDATA[With web services used everywhere, being able to parse XML is a necessary skill when developing Android apps. Here&#8217;s an example for you to modify for your own purposes.

General app set-up:
I suggest you create a separate class to handle all your parsing, and call it &#8220;MyProjectXMLParser&#8221; or similar. Personally, I even like to go as [...]]]></description>

Man1 &#8220;What are they?&#8221;
Man2 &#8220;They are like the iPad I think.&#8221;
