1. what grammar is used to select nodes?
There is no grammar to select nodes, but see filtering below.
2. how is node filtering done?
The NodeFilter class and its subclasses are used to say whether a node should be included in the output NodeList.
There are various combining filters too, like AndFilter and OrFilter.
3. what does the Parser class do (detailed tasks)
The parser doesn't do much it's mostly a locus for high level input... what URL, what error reporting etc.
The detailed work is in the Lexer and Scanner classes.
4. what is the function of NodeList?
An ordered collection of nodes. In generic collection speak it is a List<Node>.
