less then or greater then sign in output returns BAD XML when trying to send via send_nrdp.sh

[lionkg]

While trying to send data via stdin in bash like this
echo -e "server_name\tcheck_name\t0\result is < 100\n" | ./send_nrdp.sh -t token -u https://url/nrdp
server returns an error message:
ERROR: The NRDP Server said BAD XML
Removing less then sign solves the problem.
