[xsl] Removing if no data - iterating through every child (sorry the codes a bit long)

["Kevinjohn Gallagher" <web_design_guru@xxxxxxxxxxx>]

Initially, sorry for the code seeming long. But it's a bit of a follow up to 
yesterdays questions (which I solved thanks to y'alls help).



Ok, so I have an XML file, where I can have any number of nodes, which can 
have any number of Children (and they can have children and so on).

Basically, I want to strip a node if it or it's children has no data, or has 
no attributes with data anywhere in it's descendants.

I sort of get the logic, but fail miserably to even consider how to fix it 
so that the last example works (Checkbox 6) - ie. Stripping a tree half way 
down.

ANY help would be great.

Thanks ALot

Bryan.

P.S. the number of children in the example is not overkill, there will 
usually be at least 4 - sorry.
