Syntax for printing the vulnerblities

[Sohel1999]

Hello,
I try to print out VULNERABLITIES from .xml file unsuccessfully.
I have vulnerblity in my Result.xml file.
I want to print that vulnerblity but i unable to do can you plz guid me.

This is my code for printing Host and Services:

python_libnmap==0.7.3
python==3.8.10

from libnmap.parser import NmapParser

nmapparser = NmapParser.parse_fromfile("Result.xml")
print("Nmap scan summary: {0}".format(nmapparser.summary))

for host in nmapparser.hosts:
    print('Host : {0} '.format(host))
    print('Services: ')

    for serv in host.services:
        print('Service : {0} '.format(serv))

Output:

Nmap scan summary: Nmap done at Fri Jan  6 18:59:32 2023; 1 IP address (1 host up) scanned in 80.16 seconds
Host : NmapHost: [0.0.0.0 () - up] 
Services: 
Service : NmapService: [open 25/tcp smtp ()] 
Service : NmapService: [open 80/tcp http ()] 
Service : NmapService: [open 2000/tcp cisco-sccp ()] 
Service : NmapService: [open 8291/tcp unknown ()] 

similarly i tried for vulnerblity but i failed

This is code:

print(host.scripts_results)
for script_out in host.scripts_results:
    print("Output of {0}: {1}".format(
        script_out['id'], script_out['output']))

Output was empty but my .xml have vulnerblities.
Can i get valid syntax for printing the vulnerblities.

Thank You.
