See the below query. The only tricky part is using the ./ to get the ancestor values.
select poductcode, model, color, storage, Manufacturer, Supplier
from test_table t
cross join xmltable
(
'/Supplier/Electronics/Vendor'
passing xmltype(t.a_clob)
columns
PoductCode varchar2(4000) path 'PoductCode',
Model varchar2(4000) path 'Phones/Model',
Color varchar2(4000) path 'Phones/Color',
Storage varchar2(4000) path 'Phones/Storage',
Manufacturer varchar2(4000) path './../Manufacturer',
Supplier varchar2(4000) path './../../SupplierName'
) phones;
