[rules-users] Is it possible to retrieve the collection of Conditions from DecisionTable?

[Wolfgang Laun]

A condition does not have a "name", as you write; values of the cells
below a condition are (usually) literals.

There is no API for extracting parts of a spreadsheet. You can look at
the Drools source code (in the packages org.drools.decisiontable and
.../parser) and write whatever you need - it is not too difficult.
