[Bioperl-l] TIGR xml parser(s)

[Josh Lauricha]

I asked TIGR about that awhile ago and those are in-progress files,
whereas the one tigr.pm parser handles what those will become when they
are released. O. stativa is a good example of this, avilible in both [1]
which is parsable with tigr.pm and in [2] which has the coordset files.
How is the memory usage in XML::SAX? If its not bad maybe I'll redo
tigr.pm with that. I'd love not to be using regex to parse the thing.
