#data =  soup('table')[2].tbody('td',{'class':'valid'})[1].get_text()
dataPower =  soup('table')[2].tbody('td')[10].get_text()

It can be done by adding the library directory to the lib search path:

Code: [Select]


import sys
sys.path.append("/usr/lib/python2.7/")


for more info about the Python engine used in HG see:

Hy Gene

With the following code

Code: [Select]

"""
Python Automation Script
Example for using Helper Classes:
hg.Modules.WithName('Light 1').On()
"""
import sys
sys.path.append("/usr/lib/python2.7/")
import urllib2
from bs4 import BeautifulSoup

soup = BeautifulSoup(urllib2.urlopen('http://192.168.1.64/listdev.htm').read())
#data =  soup('table')[2].tbody('td',{'class':'valid'})[1].get_text()
dataPower =  soup('table')[2].tbody('td')[10].get_text()
lastScan =  soup('table')[2].tbody('td')[16].get_text()

hg.Program.Notify("HelloPY",dataPower)
I get this error

Code: [Select]

Line 0, Column 0 (Program Code):
    An exception was thrown by the type initializer for CodecsInfo

Some dependency missing? Can't help much on python =/
Btw, you can use hg NetHelper class to achieve the same result:

Code: [Select]

data = hg.Net.WebService("http://192.168.1.64/listdev.htm").GetData()

if fetched data is XML or JSON then the returned value (data) is the resulting deserialized object.
Otherwise it is a string that you have to parse in some other way (and that is the case).

The problem is that, and i don't now why i can't compile c# programs

And to parse the html output i need the BeautifulSoup import and can't put it to work :/

Hi codemind,

by googling I found this:

I fixed this by installing the mono library: libmono-i18n2.0-cil

Looks like that package should be added as a dependency of the ironpython package.

so try an sudo apt-get install libmono-system-componentmodel-dataannotations4.0-cil libmono-i18n2.0-cil .

Hope this helps!

Cheers,
g.

Since this seems to be a mono bug, we can just wait.
Isn't there any BeautifulSoup alternative for parsing?
