Does there exist a preprocessor to remove test annotations, e.g. <caret>?

I am using test data files with my subclass of LightCodeInsightFixtureTestCase.

I want to use these files for multiple purposes: for use with the in-memory editor and also for parsing through another program to get an AST. However, the <caret> markup interferes with the other program's parsing. Is there a preprocessor to remove the annotations? Currently, I'm just having to keep 2 versions of each before file, e.g.:

BeforeInsertParameterWithCaret.java

public class Test {
    void drive(Car car<caret>) {
        car.start();
    }
}

BeforeInsertParameterWithoutCaret.java

public class Test {
    void drive(Car car) {
        car.start();
    }
}

AfterInsertParameter.java

public class Test {
    void drive(Car car, int distance) {
        car.start();
    }
}
