python - How to install module for BeautifulSoup XML parsing?

Question

In this answer, I was told to not use BeautifulSoup(xmlData, 'html.parser') for XML parsing but to use BeautifulSoup(xmlData, 'xml'). That parser, however, does not come with BeautifulSoup.

As per one of the comments, I tried:

python -m pip install lxml

But got:

I am using Python 3.5.2 and would like something that will work right out of pip, meaning won't need to be compiled separately.

Answer 1

You would need a compiler on Windows to install lxml through pip.

Some unofficial builds are available here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

Find URL for the right wheel package then this should work:

pip install http://url_to_wheel
