BeautifulSoup supports multiple html parsers. Some of those parsers try to make the html valid by adding/removing tags[1]. This can lead to useless html, head & body tags in the final document. By explicitly setting the parser to ’html.parser’ this behaviour can be avoided. [1] http://www.crummy.com/software/BeautifulSoup/bs4/doc/#differences-between-parsers

Why do you need it?
Pelican can generate ToC of reST and Markdown files, using markup's respective
directive and extension. ToC is generated and placed at the beginning of
article.content. You cannot place the ToC in <nav> HTML5 tag, nor can you
place the ToC at the end of your article's content because ToC is part of
article.content.
This plugin extracts ToC from article.content and places it in article.toc.
Requirements
extract_toc requires BeautifulSoup.
pip install beautifulsoup4
How to Use
Important! This plugin only works with reST and Markdown files. reST files
should have .rst extension. Markdown files can have .md, .mkd or
markdown.
If ToC appears in your article at more than one places, extract_toc will
remove only the first occurrence. You shouldn't probably need to have multiple
ToC in your article. In case you need to display it multiple times, you can
print it via your template.
ToC generated by Markdown is enclosed in <div class="toc">. On the other hand
ToC generated by reST is enclosed in <div class="contents topic">.
extract_toc relies on this behavior to work.
reStructuredText Example
To add a table of contents to your reStructuredText document you need to add a 'contents directive' at the place where you want the table of contents to appear. See the documentation for more details.

Markdown Example
To add a table of contents to your Markdown document you need to place the 'TOC marker' at the place where you would like the table of contents to appear. See the Python Markdown documentation for more details.
Important! To enable table of contents generation for the markdown reader you need to set MD_EXTENSIONS = (['toc']) in your pelican configuration file.
