get_actual_text

Obtains the actual text enclosed by the element (and its child elements).

The actual text is mostly used for non-text elements like images and figures which do have the graphical appearance of text, like a logo. For those the actual text is the equivalent text to those graphical elements which look like text when rendered.

Note that for elements containing proper text, the function get_text must be used instead.

Parameters:

this	A StructureElement

Returns:

The actual text for the element, or null if not defined.
