Stripping html from form inputs

Rails
1

Ahoy m8ies,

Quick question.

Is there any existing demo code or a library which handles stripping
unwanted tags from form fields?

Also, a form might allow image tags, but we might want to strip out
any paramters other than SRC ?

Anohter issue is how handle inputs such as these:

  • 1 is less than 2
  • 1 is < than 2

In the second case, we need to guess that < is not opening a tag, and
convert it to a special character.

Thanks for any ideas or links!

You might look at strip_links and strip_tags

Also, look at the tidy library and gem
