Re: parent node ??

= testing on a node tests its string value, ie the concatenation of all
character data, ignoring markup.

in
solution/valid_input[parent::solution = self::valid_input]

since inside the predicate teh parent is always going to be solution and
the current node valid_input (as that is the select expression before
the predicate) this is the same as

solution/valid_input[.. = .]
which will select all valid inputs that have the same string value as
there parent, which is only possible if any siblings of that element
have an empty string value (since the string value of the parent is the
concatenation of the values of the siblings)

since you didn't say what you were trying to count I can't suggest how
to change this.

If you just deleted the predicate and had count(solution/valid_input)
you'd get the number of valid input but I don't know if that's what you
intended.
