[PATCH] c14n samples

[Keith Beattie <KS...@lbl.gov>]

Hi all,

I've made a few changes to the c14n samples that I've found helpful in testing.  On the chance that this is considered helpful to others, here are my patches (`cvs diff -u` output is acceptable?):

The changes are:

1) Adding CanonDirect, CanonByTransform & CanonSubTree targets to build.xml

2) Changing those three sample programs to check for the existance of a specific input file and read from that if it exists, otherwise it behaves as before.  Also added the c14n constants for easy changing from one kind of c14n to another.

Cheers,
ksb
