Trying to use python-nmap but receiving however python2 or 3 can't find PortScanner.

[PythonNmap]

Hmm, I've changed the function name but same result.

#!/bin/python
 
import sys
import getopt
import nmap
 
import xml.dom.minidom, xml.etree.ElementTree as et;
 
def nmapScan(vlan, netmask):
    # NMAP VLAN to determine IP availability.
    print ("NMAP Scanner")
    nm = nmap.PortScanner ()
 
 
def main():
    xmltree = et.parse(sys.argv[1]);
 
    # XML Tree Item = xti
    for xti in xmltree.iter('AR'):
        network_address = xti.find('NETWORK_ADDRESS').text;
        network_mask = xti.find('NETWORK_MASK').text;
 
        print ("[*] Network Address: ", network_address);
        print ("[*] Network Mask: ", network_mask);
 
    nmapScan(network_address, network_mask)
 
if __name__ == "__main__":
    main();

Error:
$ ./ip-get.py vlan2.xml
[*] Network Address:  10.0.0.117
[*] Network Mask:  255.255.255.0

    nm = nmap.PortScanner ()

Thx,
