Target of Items from a path

I am displaying a list with path (fe. musicdb://) as contents. What is the property that allows to determine what is the path of an element of such list (fe. musicdb://songs/ or something defined with Library Node Editor)? I’ve looked at ListItem $INFOs – but cannot see it there.

The idea is to add <onclick> for the list in order to open MyMusicNav window already with the selected scope.
