frag2text
=========

        :target: https://pypi.python.org/pypi/frag2text/

Markdown_ gives you HTML from plain text and html2text_ reverses the
process. If you want the plain text version of *a specific section* of
a web page (an HTML fragment), you would normally do the selecting
(parsing) first, then generate the Markdown text to preserve some
formatting.

I made *frag2text* to:

* easily select a web page fragment by CSS selector or XPath
  expression
* get the plain text of the fragment with some formatting intact for
  later use with Markdown
* not shell out to a another program (like lynx -dump)
* not parse HTML or text directly
* use html5lib for robust parsing
* have a simple python module that is easy to maintain (encapsulating
  the tricky business of subclassing parsers, treebuilders and
  serializers, by keeping it simple – this shouldn't require
  BeautifulSoup) 

This is a problem I've tinkered with for some time and solved in many
different ways. It seems trivial but gets ridiculous quickly. If you
have any suggestions or want to share your experiences with other
tools, please let me know.
