There are several possible ways to achieve that.

If you are using Python 2.5 or newer, the simplest way is field 
expr="currentvalue if ru.oCurrentvalue else lastpurchaseprice".

You may also do it using template conditionals:

     <field expr="currentvalue">
      <style printwhen="ru.oCurrentvalue" />
     </field>
     <field expr="lastpurchaseprice">
      <style printwhen="not ru.oCurrentvalue" />
     </field>

Finally, you may create a Python module with any functions you need and 
import it into your template.
