filtering content 2.0

So, here we go.

Basicly this is the situation I’m dealing with: my ‘single’ page is a gallery + textual info.

What I want is to
– always show the gallery
– to make a button which enables to show the ‘textual info’ by clicking on it. Which is jquery and not the issue.

The problem I run into:
– the gallery is a nice container (div) (good)
– the content isn’t contained, so I can’t manipulate that.

I thought of:
– putting my content in my article, insert the ‘!more’ tag and adjust the ‘single’ loop to ‘<div> the_excerpt() </div> and the_content(”, true).

But that just doesn’t give me enough possibilities for positioning my elements.

Isn’t there a ‘better’ approach which enables me to filter the content? so my output would be

<div class="content"> My content goes here</div>
<div id="gallery"> My wp gallery goes here</div>

?

Curious for your thoughts / suggestions!
