finding sidebar content in wordpress

The content for a dynamic sidebar is whatever widgets are added to that sidebar from the backend. Look at wp-admin->Appearance->Widgets. The actual code for those widgets could come from WordPress itself, a plugin, or your theme.

But…

The content that i am interested in goes inbetween the < div
class=”visual”> and the < div class=”visual-holder”>

.. nothing goes between those two <div>s. They are hard coded to be nested like that. Your content is inside the second one, which is inside the first.
