  xmlcharref = Regex('&#\d+;')

  """
/usr/local/lib/python3.7/site-packages/pkg_resources/_vendor/pyparsing.py:2914: DeprecationWarning: invalid escape sequence \g
  ret = re.sub(self.escCharReplacePattern,"\g<1>",ret)

I upgraded PyParsing to 2.2.0 and these warnings still persist.

@winash12 How did you upgrade PyParsing? What did you run to check the warnings?

Here's one way:

I downloaded PyParsing 2.2.0 and I installed it in the following way
python3.6 setup.py install as root.

Then I ran my script and I got those warnings.

@winash12 Please paste your output.

Setuptools doesn't use PyParsing from the usual install location, but packages its own.

You can replace your file at something like /usr/local/lib/python3.6/site-packages/pkg_resources/_vendor/pyparsing.py with the one in this PR.

Yes I got that but I do not have that directory under /usr/local/lib/python3.6/dist-packages/setuptools-40.0.0-py3.6.egg

The file etuptools-40.0.0-py3.6.egg is not a directory. Should I download setuptools and reinstall on my own ?

[hugovk]

Let's wait for review from a project member :)

[pganssle]

Regardless of the warnings, the tests pass and I see no reason not to upgrade this. Merging.
