While waiting for a integrated solution. Here is a function that should do the job in a safe way. It returns an iterator

````
def xndindex(ds, dims=None):
    if dims is None:
        dims = ds.dims
    elif type(dims) is str:
        dims=[dims]
    else:
        pass
        
    for d in dims:
        if d not in ds.dims:
            raise ValueError(""Invalid dimension '{}'. Available dimensions {}"".format(d, ds.dims))
            
    iter_dict = {k:v for k,v in ds.sizes.items() if k in dims}
    for d,k in zip(repeat(tuple(iter_dict.keys())),zip(np.ndindex(tuple(iter_dict.values())))):
        yield {k:l for k,l in zip(d,k[0])}
  
````
Example of use
````
a = xr.DataArray(np.random.rand(4,3), dims=['x','y'], coords={'x':np.arange(4), 'y':np.arange(3)})
for i in xndindex(a):
    print(a[i])

For now, when I want to iterate over all my dataset I use the simple (but dangerous I believe) workaround:
````
for i in np.ndindex(ds.shape):
        res = ds[{d:j for d,j in zip(ds.dims,i)}]
````
but, I am not sure that ndindex will iterate in the good order relatively to the ds.dims return.

Is there any news on this topic ?

Many thanks !","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,419543087

Converting the xarray to a DataFrame indeed does the job and I will use this solution for the time being. Nevertheless, to me the approach seems rather like an ad-hoc solution since it requires a series of conversions / function calls and I feel like there should be some built-in solution from xarray. In particular, in the above solution, you lose track of what are the coordinates and what is the actual data (all is stored in a single NamedTuple), which requires an additional step to separate the two data structures. Anyway, thanks for your help! If you find another solution, please let me know!","{""total_count"": 3, ""+1"": 3, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,419543087

```python
import xarray
import itertools

ds = xarray.tutorial.open_dataset('air_temperature')
records = ds.to_dataframe().reset_index().itertuples(index=False, name='Record')
print(list(itertools.islice(records, 5)))
```
Outputs:
```
