Strip html from string Ruby on Rails
Solution 1:
If we want to use this in model
ActionView::Base.full_sanitizer.sanitize(html_string)
which is the code in "strip_tags" method
Solution 2:
There's a strip_tags method in ActionView::Helpers::SanitizeHelper:
http://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-strip_tags
Edit: for getting the text inside the value attribute, you could use something like Nokogiri with an Xpath expression to get that out of the string.
