55cd82008e Rewrite protection against JavaScript injection
This drops the naive approach at <script> tag stripping and resorts to
full sanitization of html. The general idea (and the regexps) is grabbed
from Stack Exchange's PageDown JavaScript Markdown processor[1]. Like in
PageDown, it's implemented as a separate pass over resulting html.

Includes a metric ton (but not all) of test cases from here[2]. Several
are commented out since they don't pass yet.

Stronger (but still incomplete) fix for #11.

6e6572e913 Added th to table headers so that styling with things like Twitter Bootstrap and typeset.css work as expected. Cells in headers should always be TH unless they are advisory cells within headers in which case TD is acceptable (but being Markdown a user with such needs could just enter HTML for this) 2013-10-16 11:36:33 +01:00

c23099e5ee Implementation and some tests for inline footnotes. Also I noticed the list items had the wrong ids, that was silly of me. 2013-07-01 01:37:52 +00:00

d5a8df164b Fix bug in isHtmlTag()
Fix what seems to be a typo. j should iterate through all tagname, so it
should be initialized to zero. The test exposes this bug.
