I have two dataframes structured like this:

```
X A  B  C SUM
E 1  0  1  2
F 0  0  1  1
G 1  1  0  2

```

and this:

```
X A  B  C SUM
E 1  0  1  2
F 0  0  1  1
G 1  1  0  2
H 0  0  1  1
I 0  0  0  0

```

The result that i want to obtain is:

```
 X A  B  C   
 H 0  0  1 

```

So, i want a code which is able to create another dataframe **made by only those rows which are not present in both dataframes**. Moreover, the sum of these rows has to be **more than zero**.

Could someone help me?
Thank You!
