It was already broken and didn't work properly, but update to py3 and at least make it run. More changes are necessary to actually make it happy again.

# localhtmlvalidate.py - validate local HTML for pgweb
|
|
#
|
|
# This is a small tool that you run to validate the HTML output of your
|
|
# localhost pgweb installation against the W3C validator. Give it the
|
|
# localhost:8000 URL (or other, depending on what port you're running the
|
|
# local server on), and it will give you a list of possible issues with
|
|
# the page.
|
|
#
|
|
# In theory it can be used just fine for non-pgweb pages as well, but
|
|
# for obvious reasons the functionality to show the source line number
|
|
# based on the pgweb templates won't work.
