# Script to deploy certificates to Palo Alto Networks PANOS via API
# Note PANOS API KEY and IP address needs to be set prior to running.
# The following variables exported from environment will be used.
# If not set then values previously saved in domain.conf file are used.
#
# Firewall admin with superuser and IP address is required.
#
# REQURED:
#     export PANOS_HOST=""
#     export PANOS_USER=""    #User *MUST* have Commit and Import Permissions in XML API for Admin Role
#     export PANOS_PASS=""
#
# The script will automatically generate a new API key if
# no key is found, or if a saved key has expired or is invalid.

# This function is to parse the XML response from the firewall
