click_element/click_link when I don't have an id

The HTML code for it:
<li><a href="http://maps.skobbler.com/">Maps</a><span class="beta-tag">beta<span></span></span></li>

Whenever you don't have the ID for an element, use a get_element to find it. For example, here you'd use click_element or click_link with a nested get_element in it:

click_element(get_element(tag='a', href='http://maps.skobbler.com', text='Maps'))
