Martin Probst 41251715ad Use go.net/html's parser to sanitize HTML.
Use an HTML5 compliant parser that interprets HTML as a browser would to parse
the Markdown result and then sanitize based on the result.
Escape unrecognized and disallowed HTML in the result.
Currently works with a hard coded whitelist of safe HTML tags and attributes.

willnix be9cbc634a tagWhitelist allows alignment attribute now
This is the closest I could get to removing everything "unsave" without introducing an additional regex.

willnix c1e4996787 Add table tags to the whitelist.
Fixing:
55cd82008e

This commit introduced a html tag whitelist which does not include any table tags (<td>,<tr>,<thead>...). Therefore even tables the markdown parser itself generated will be removed.

Vytautas Šaltenis b0bdfbec4c Fix bug in autolink overescaping html entities
If autolink encounters a link which already has an escaped html entity,
it would escape the ampersand again, producing things like these:
    &amp;  --> &amp;amp;
    &quot; --> &amp;quot;
This commit solves that by first looking for all entity-looking things
in the link and copying those ranges verbatim, only considering the rest
of the string for escaping.
Doesn't seem to have considerable performance impact.
The mailto: links are processed the old way.

Vytautas Šaltenis cc0d56d092 Extract a chain of ifs into separate func
This gives a ~10% slowdown of a full test run, which is tolerable.
Switch statement is still slightly slower (~5%). Using map turned out to
be unacceptably slow (~3x slowdown).

Vytautas Šaltenis 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.

David Kitchen 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

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.
