I have controller in web2py as below
# coding: utf8
# try something like
#!/usr/local/python2.7
def index():
import pexpect
import sys
import time
import cgi, cgitb
import getpass
import urllib3
import elementtree.ElementTree as ET
ssh_cmd = 'ssh -t'
username = 'admin'
ip_addr = '192.***.***.***'
login = 'logging root'
password = 'password'
command = ssh_cmd+" "+username+"@"+ip_addr+" "+login
try:
child = pexpect.spawn(command)
child.expect('(?i)password')
child.sendline('admin')
child.expect('(?i)Password:')
child.sendline('abghtnnppst')
child.expect('-bash# ')
child.sendline('cd /root/siby')
child.expect('-bash# ')
child.sendline('perl analyzer_main.pl -s -i all')
child.expect('-bash# ')
except Exception, e:
print e
print child.before
lines = child.before
results = ET.Element("results")
for line in lines.split("\n"):
if 'MAC' in line:
station = ET.SubElement(results,"machine")
stnmac = ET.SubElement(machine,"mac")
stnip = ET.SubElement(machine,"ip")
apidname = ET.SubElement(machine,"name")
totalxput = ET.SubElement(machine,"input")
retry = ET.SubElement(machine, "retry")
if 'MAC' in line:
mac = line.split(":", 1)
mac.text = str(mac[1].strip())
if 'IP' in line:
ip = line.split(":")
ip.text = str(ip[1].strip())
if 'NAME' in line:
name = line.split(":")
name.text = str(name[1].strip())
if 'input' in line:
input = line.split(":")
input.text = str(input[1].strip())
if 'Retry' in line:
ret = line.split(":")
retry.text = str(ret[1].strip())
tree = ET.ElementTree(results)
tree.write('station.xml')
sys.stdout.flush()
if child.isalive():
child.sendline('exit') # Try to ask ftp child to exit.
child.close()
if child.isalive():
print('Child did not exit gracefully.')
else:
print('Child exited gracefully.')
xmlstr = ET.tostring(tree,encoding=None)
return dict(xmlstr)
In View I have the following code
{{extend 'layout.html'}}
<h1>This is the remotectrl/index.html template</h1>
<body>
{{=XML(xmlstr)}}
</body>
{{=BEAUTIFY(response._vars)}}
I want to print the XML data in webpage index.html
But it is giving me exception

Not sure what is the issue here, why is it not printing XML data in to index.html ?
Thanks for help

your issue is with this line...
xmlstr = ET.tostring(tree,encoding=None)
might want to try it out in your python repl before modifying your controller.
