* @note: this class uses a different naming for each part of a xml:
* <channel />
*    <node />
*       <item />attribute value</item>
*       <attribute2 property="attribute value">item value</item2>
*    </node>
*    <node2 />
*       <item />attribute value</attribute>
*       <item2 attribute="attribute value">item value</item2>
*    </node2>
* </channel>
*
* I know these names aren't the standard. But that's the way i've learned :P enjoy this class
