I did not understand what you were exactly looking for but
if you have any questions about rpm-analyzer I'll be glad to
answer.
The following example may help, though.
rpmtest.py
------------------------------------------------------------------
#!/usr/bin/python
import rpm, sys, os
if len(sys.argv) != 2:
sys.stderr.write("Usage: %s <rpmfile>\n" % sys.argv[0])
sys.exit(1)
file=sys.argv[1]
ts = rpm.TransactionSet("", rpm._RPMVSF_NOSIGNATURES)
fd = os.open(file, os.O_RDONLY)
hdr = ts.hdrFromFdno(fd)
print "package name : ", hdr[rpm.RPMTAG_NAME]
print "package version: ", hdr[rpm.RPMTAG_VERSION]
os.close(fd)
------------------------------------------------------------------
you may find all RPMTAG_ values into the 'maximum rpm' document.
