How to fix this AttributeError?

I installed a stripe package yesterday and now my app is not running. I am trying to understand where the problem is. Is it something to do with

or something else. I am posting with GAE tag as well hoping that the trace from logs may give a clue about the problem:

MLStripper instance has no attribute 'rawdata'
Traceback (most recent call last):
File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/_webapp25.py", line 703, in __call__
File "/base/data/home/apps/ting-1/1.354723388329082800/ting.py", line 2070, in post
pitch_no_tags = strip_tags(pitch_original)

File "/base/python_runtime/python_dist/lib/python2.5/HTMLParser.py", line 107, in feed
self.rawdata = self.rawdata + data
AttributeError: MLStripper instance has no attribute 'rawdata'

This is MLStripper:

from HTMLParser import HTMLParser

class MLStripper(HTMLParser):
def __init__(self):
self.fed = []
def handle_data(self, d):
def get_data(self):
return ''.join(self.fed)

def strip_tags(html):
s = MLStripper()
return s.get_data()

MLStripper was working fine until yesterday.

And these are my other questions:

How to fix this AttributeError with HTMLParser.py

How to fix a corrupted PyShell.py


There are one or two issues with the code you posted (mainly to do with initializing the HTMLParser properly).

Try running this amended version of your script:

from HTMLParser import HTMLParser

class MLStripper(HTMLParser):
    def __init__(self):
        # initialize the base class

    def read(self, data):
        # clear the current output before re-use
        self._lines = []
        # re-set the parser's state before re-use
        return ''.join(self._lines)

    def handle_data(self, d):

def strip_tags(html):
    s = MLStripper()
    return s.read(html)

html = """Python's <code>easy_install</code>
 makes installing new packages extremely convenient.
 However, as far as I can tell, it doesn't implement
 the other common features of a dependency manager -
 listing and removing installed packages."""

print strip_tags(html)
