Yes, i read the docs... maybe it was too much input in a short time! 
I try to make it more clear what i want. As an element i mean now an
element as in the DTD.

<!ELEMENT fw-input-rule (action, protocol, from-ip, from-port, to-ip,
to-port, log)>
<!ELEMENT action (#PCDATA)>
<!ELEMENT protocol (#PCDATA)>
<!ELEMENT from-ip (#PCDATA)>
.
.
.

So it should be possible to delete a "fw-input-rule node" but not an 
"action node".

Is there an easy way to distinguish between elements who have other "child 
elements" and elements who are just a leaf?
