html2markdown

Experimental

Purpose: Converts html to markdown while preserving unsupported html markup. The goal is to generate markdown that can be converted back into html. This is the major difference between html2markdown and html2text. The latter doesn't purport to be reversible.

Usage example

import html2markdown
print html2markdown.convert('<h2>Test</h2><pre><code>Here is some code</code></pre>')

Output:

## Test

    Here is some code

Information and caveats

Does not convert the content of block-type tags other than `<p>` -- such as `<div>` tags -- into Markdown

It does convert to markdown the content of inline-type tags, e.g. <span>.

Input: <div>this is stuff. <strong>stuff</strong></div>

Result: <div>this is stuff. <strong>stuff</strong></div>

Input: <p>this is stuff. <strong>stuff</strong></p>

Result: this is stuff. __stuff__ (surrounded by a newline on either side)

Input: <span style="text-decoration:line-through;">strike <strong>through</strong> some text</span> here

Result: <span style="text-decoration:line-through;">strike __through__ some text</span> here

Except in unprocessed block-type tags, formatting characters are escaped

Input: <p>**escape me?**</p> (in html, we would use <strong> here)

Result: \*\*escape me?\*\*

Input: <span>**escape me?**</span>

Result: <span>\*\*escape me?\*\*</span>

Input: <div>**escape me?**</div>

Result: <div>**escape me?**</div> (block-type)

Attributes not supported by Markdown are kept

Example: <a href="http://myaddress" title="click me"><strong>link</strong></a>

Result: [__link__](http://myaddress "click me")

Example: <a onclick="javascript:dostuff()" href="http://myaddress" title="click me"><strong>link</strong></a>

Result: <a onclick="javascript:dostuff()" href="http://myaddress" title="click me">__link__</a> (the attribute onclick is not supported, so the tag is left alone)

Limitations

Tables are kept as html.
