[Bioperl-l] NCBI Genbank ID to TaxonID via Bioperl?

Dear All,

For a list of approx. 20 GI numbers (NCBI GenBank IDs) I need the taxon 
ID as given in the corresponding full GenBank record. Which is the 
easiest way to accomplish this task automatically? Does Bioperl help? 
Can one access this function via the NCBI website (possibly, using 
Bioperl)? Or, does one have to download the whole GenBank database?

All I could find out is that there is a function 'gi2taxid' in the NCBI 
toolkit, but I have no experience with using the toolkit, and I hope 
that there is an easier 'Bioperl' way to solve the problem - could 
BIO::DB::NCBIHelper be the way to go? Any help or hints are greatly 

Kind regards,

Michael Spitzer
