Request - How to fetch JSON

Hello,

I am playing around with the default skin and wondering how to make dynamic menu.

As of now it looks like this.

<content>
                        <item>
                            <label>Menu1<label>
                            <property name="menu_id">$NUMBER[6000]</property>
                            <thumb>icons/sidemenu/tv.png</thumb>
                            <property name="id">tvshows</property>
                            <visible>!Skin.HasSetting(HomeMenuNoTVShowButton)</visible>
                        </item>
                        <item>
                            <label>Menu2</label>
                            <property name="menu_id">$NUMBER[6000]</property>
                            <thumb>icons/sidemenu/tv.png</thumb>
                            <property name="id">tvshows</property>
                            <visible>!Skin.HasSetting(HomeMenuNoTVShowButton)</visible>
                        </item>
                       
</content>    

Ideally I like to fetch from URL and show item tag as many as received data length. Something like foreach method. Then inside "label" tag "item.name" so that it would converted to string.

How can I do this in Kodi skinning?
