Oracle dump, load to same table with new schema

I'd like to perform an oracle dump of my data and then load it back in after re-installing the software. 

The problem is however that as I re-install the software, the schema of the data which I just exported may have changed slightly. 

In mysql, I would hand-edit the SQL formatted dump file before importing it to match any schema changes. 

But Oracle uses a proprietary dump/load format :( 

Any tricks to preserving my data? Thanks!
