in some functions in theme-base output text is already generated, such as:
function post_meta_when($post, $class)
value of $post['when'] is like :
<SPAN CLASS="published"><SPAN CLASS="value-title" TITLE="2012-10-07T21:31:48+0000"></SPAN>3 days</SPAN>
so, how can I get direct access to information inside span tag?
Where this output is generated? can it be replaced with another function for some case?
