Yes, I'm aware about SDOM. Sorry, I've forgotten to reference it. I'll fix
it in the next revision of the text.

DOM is something I definitively avoid to use. Using DOM in programs is
like programming in assembler, except the latter is fun, but the former is
only tiresome coding.

Or, in other words, from one of the early responses on SDOM:

Presumably, you are aware about the paper "On parent pointers in SXML
trees".

Interesting. Do you mean, if I have "node1" and "node2", SDOM can say if
"node1" comes before or after "node2"? If yes, would you please describe
how you implemented it?
