# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# The signed XML to be verified in this example contains the following:

# <?xml version="1.0" encoding="ISO-8859-1"?>
# <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
# <Documento ID="F13T34">
# ...
# </Documento>
# <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
# ....
# </Signature>
# </DTE>

# Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1
