Python - Error Parsing HTML w/ BeautifulSoup

I'm developing an app that inputs data onto a webpage shopping cart and verifies the total. That works fine, however, I am having issue with parsing the HTML output.

A previous discussion; retrieving essential data from a webpage using python, recommended using BeautifulSoup to make solve said user's problem.

I've borrowed some of the python code, and got it to work on a MacOS system. However when I copied the code over to an ubuntu installation, I'm seeing a strange error.

**The Code (where I'm seeing the issue):

response = opener.open(req)
html = response.read()
doc = BeautifulSoup.BeautifulSoup(html)

table = doc.find('tr', {'id':'carttablerow0'})

dump = [cell.getText().strip() for cell in table.findAll('td')]

print "\n Catalog Number: %s \n Description: %s \n Price: %s\n" %(dump[0], dump[1], dump[5])

**The Error ( on the ubuntu server)

    Traceback (most recent call last):
      File "./shopping_cart_checker.py", line 49, in <module>
        dump = [cell.getText().strip() for cell in table.findAll('td')]
    TypeError: 'NoneType' object is not callable

I think I've narrowed it down to getText() being the culprit. But I'm not certain why this works on MacOS and not ubuntu.

Any suggestions?

Thank you.

Hi Guys,

Thank you for the various suggestions. I've attempted most of them, (incorporating the "if cell" statement into the code, however it still i开发者_JAVA百科sn't working.

@ Ignacio Vazquez-Abrams -- Here's a copy of the HTML I'm attempting to strip:

As to why it doesn't work on Ubutntu, no idea. However, you can try this:

dump = [(cell.getText() if cell.getText() else '').strip() for cell in table.findAll('td')]

It doesn't seem to be a problem with the code but with the HTML you are reading, what I would do is changing your code to do this:

dump = [cell.getText().strip() for cell in table.findAll('td') if cell]

That way if cell is None it will not try to execute getText and just skip that cell. You should debug if you can, i recommend you to use pdb or ipdb (the one i like to use). Here is a tutorial, with that you can stop just before the line and print values, etc.
