[Swftools-common] Replace a string

[Roger Chinchilla]

I would like to know if there exists a way to change text at the time of conversion. I am currently importing a file and converting it to SWF but there exists a specific string that I would like to change:

Copyright 2009 and I would like to change it to Copyright 2000-2009. Is there any way to identify "Copyright 2009" and assign a replacement at the exact same starting position?

Changing the source document before importing is not an option.
