I should've examined more before I post a questions here.
I've attached what I thought was ASCII-encoded data, which is quite
different from what you have imagined. TLV fields are not explicitly
represented in the data. I think this is an application-specific output
and only customized parser can do the job I've wanted.
Am I missing something here?
BTW, this is only a tiny part of the entire database of CCSD (Complex
Carbohydrate Structural Database). The database contains the information
on complex oligosaccharide like the types of sugar units, glycosidic
linkages, links to literature, etc.

Keishi
