Upon running my python script I am getting following error
File "myfile.py", line 538, in parse_format_views_into_memsource_json
page_soup = BeautifulSoup(page, 'xml')
File "C:Python27libsite-packagess4\__init__.py", line 246, in __init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: xml. Do you need to install a parser library?
After reading a few posting about bs4, I changed the xml to lxml like below.
page_soup = BeautifulSoup(page, 'lxml')
Now I am getting the same error for lxml
File "myfile.py", line 538, in parse_format_views_into_memsource_json
page_soup = BeautifulSoup(page, 'lxml')
File "C:Python27libsite-packagess4\__init__.py", line 246, in __init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?
I am very puzzled about this situation. I checked my pip list and surely I do have lxml. The list below.

virtualenv (15.1.0)
wheel (0.30.0)
Am I missing anything here?
==== Update ===
I have checked import on lxml. Although I pip installed lxml, I cannot import lxml or lxml.etree. What makes more confusing is that I can import bs4 without any problem. I pip installed them at the same time and the same manner. I don't know how to proceed from here.
I checked the pip package list again, this time from the script itself using following command.
import pkg_resources
print([p.project_name for p in pkg_resources.working_set])
It clearly shows that there lxml is available the the Python instance I am using. Below is the output
