Snippet List
Sanitize text field HTML (here from the Dojo Toolkit Editor2 widget)
When using a JavaScript WYSIWYG editor widget for text area content, the resulting HTML should be sanitized so no unallowed HTML tags (esp. script tags) are present. The [BeautifulSoup](http://www.crummy.com/software/BeautifulSoup/) library handles HTML processing in the solution presented above, so you should place it in the Python path. The snippet also assumes that you have [the Dojo Toolkit](http://dojotoolkit.org/) and its Editor2 widget loaded on your page. **Note**: this snippet was originally written for use with Dojo Toolkit 0.4, and it hasn't been updated for 0.9 or 1.0.

Sanitize HTML filter with tag/attribute whitelist and XSS protection
Reworked version of [this snippet](http://www.djangosnippets.org/snippets/205/) that now accepts an argument so the user can specify which tags to allow, and which attributes should be allowed for each tag. Argument should be in form `tag2:attr1:attr2 tag2:attr1 tag3`, where tags are allowed HTML tags, and attrs are the allowed attributes for that tag. It also uses code from [this post on stack overflow](http://stackoverflow.com/questions/16861/sanitising-user-input-using-python) to add XSS protection.

CleanCharField
I was about to start an online community but every time you allow people to post something as a comment you never know what they come up to, especially regarding profanities. So I come up with this idea, I put together some code from the old style form validators and the new newform style, plus some code to sanitize HTML from snippet number [169](http://www.djangosnippets.org/snippets/169/), and the final result is a CharField that only accept values without swear words, profanities, curses and bad html. Cheers.
