You should write preceding-sibling::item/metadata/solution. Even then, with multiple solutions in one item, it's wrong. It will select all the solutions in one item if none of them is the same as a solution in a previous item; but if one solution is the same and others are different, none of them will be selected. I recommend you use the Muenchian technique instead.
