Re: XMPs...all you could possibly want...and more!

[Tim Allison]

Hi Leonard,
  I'm literally just scraping bytes out of files for now without any
parsing...so if the XMP is concealed in a compressed stream or
something more interesting, I'm not grabbing it.  I'm also not
tracking which XMP is associated with which object.
  Please forgive me...if I traverse the COSDocument's objects and look
for /Metadata and grab the stream, will that be what you're looking
for?  Or, is there a commandline tool I can run to get what you're
interested in?
  Thank you.

  Cheers,

              Tim
