Is there Stangle/Rtangle functionality available for odfWeave input documents?

I'm using odfWeave for reproducible research and would like to extract the R code chunks form an OpenOffice .odt document in a manner similar to the way Stangle is used to extract code chunks from Sweave input files. Is this possible? 

Thanks in advance,
Denn? Reed
