I am getting an error with a python script I have created. I have 1 geodatabase with 3 feature datasets. What I would like to do, is loop through 1 feature dataset (NB) to get a list of feature classes. One by one, I would like to get the name of the feature class (ID_NB) and search for its corresponding feature class in another dataset (called CCH) so that I can perform the Intersect function on the two files and save the output in the 3rd feature dataset and call it ID_Ints. **There may not always be a matching feature dataset between the two either.
The script works fine the first time through, but when it comes to the second feature class, it gives me an error saying "Dataset does not exist or is not supported". I have a feeling it is because I have switched workspaces in a for loop, but I can't think of another way around this.
Anyone have any ideas?
