Python 3 XML parser unkown entity error

However I found a lot of answers here, unfortunately, they don't work for me.

I have Ubuntu x64, python 3.4.2.

I am parsing a web page with html entities like   among others:

import xml.etree.ElementTree as ET
page = 'some string I get from requests.get'
parser = ET.XMLParser()
parser.parser.UseForeignDTD(True)
tree = ET.fromstring(page, parser=parser)

A lot of answers contain this code in order to prevent errors like unknown entity &nbps;. While I compile this code it throws an error:

AttributeError: 'xml.etree.ElementTree.XMLParser' object has no attribute 'parser'

or

AttributeError: 'xml.etree.ElementTree.XMLParser' object has no attribute '_parser'

(depdends on what member of parser object I wrote in 4th line in the code above. The magic is when I try to go to this code from PyCharm IDE it shows me that this member is exists and successfully creates in class constructor:

# underscored names are provided for compatibility only
self.parser = self._parser = parser
self.target = self._target = target

My questions are:

1. Why does not this work ?


2. Is it possible not to add each entity manually to prevent parse errors?
