[galaxy-dev] Number of elements from a REPEAT block

Hi, I'd like to be able to ascertain the length of an array of input files captured by the REPEAT tag. For example: <repeat name="infiles"> <param name="infile" type="data" format"txt" /> </repeat> How can I get the length of $infiles to pass in my command line? Something like $infiles.length ? -- Branden Timm btimm@glbrc.wisc.edu
