[XML-SIG] Repost - disabling entity expansion

[Bill Eldridge]

Okay, as I slipped in a note in the repost,
I do have a solution in libxml2-python that
follows, so I guess I'll live with that, thanks.

#!/usr/bin/python2

import libxml2
import sys
import string

ctxt = libxml2.createFileParserCtxt("efd_1.xml")
ctxt.validate(1)
ctxt.parseDocument()
doc=ctxt.doc()
valid=ctxt.isValid()
print "VF1:",doc.docEntity("vf1").serialize()
atts=doc.docEntity("vf1").serialize().split()
ent,entfull=atts[1],string.join(atts[2:])
print "ENTITY %s: %s" % (ent,entfull)
sys.exit()
