Take your time and don't rush.

Your questions are confusing, you mix content model and actual tree. I can't answer your question it's too undefined. Where are those DTD declarations ? External DTD subset are not loaded by default. The content field of the nodes may be usable or not. And your question is not precise enough to answer <fw-input-rule><from-ip/><from-port/><to-ip/></fw-input-rule> <fw-input-rule/> have different model, I can't tell what you're considering. Did you try xmllint --debug on some of those tree to get an idea of what the structure looks like ? You must experiment because there is no way I can dump the needed informations in your brain instantly. There is a learning curve, then you will be able to ask clearer questions.
