I figured it out (in case you were still interested or curious Lee i'll
spill the beans :)
I found the way by seeking out and examining the selectCode(this) function
from the "Select All" link in the normal codebox.

if found this little beauty...
var e = a.parentNode.parentNode.getElementsByTagName('CODE')[0];
a is passed in the onclick handler as "this" like so...
<a href="#" style="color:green" onclick="runCode(this); return
false;">&#128187; Run code</a>

That gets the correct code box then e.innerText has the code with line
breaks and no html.

i used the same method to get a TextArea output element.
i can now run gambas code and display the result on my forum :)

Now i'm starting to get the idea of how things work i should be able to use
gambas highlighting too :)
