For the above example, I consider the following output,

python <xarray.Dataset> Dimensions: (nz_points: 11) Dimensions without coordinates: nz_points Data variables: x (nz_points) int64 0 0 1 1 1 2 2 2 3 3 3 y (nz_points) int64 1 2 0 1 2 0 1 2 0 1 2

It would return a xr.Dataset each keys of which are the dimension names and their values are xr.DataArray of valid indices. da[da.nonzero()] or da.isel(**da.nonzero()) would return a 1d-DataArray with non-dimensional coordinates, x and y. (nz_points is the default dimension, equivalent to da.nonzero(dim='nz_points'))

nonzero method for Dataset is not obvious, but the return of xr.DataArray.nonzero should be passed to xr.Dataset.isel().
