How to strip HTML tags including escaped image tags without ' and   stuff?

Question

I need to strip all the html elements from my content. Example of the content :

"<p><img alt=\"\" src=\"/ckeditor_assets/pictures/1/content_twitter-sink.jpg\" style=\"width: 570px; height: 399px;\" /></p>\r\n\r\n<h3 style=\"font-size: 1.38462em; margin: 1em 0px 0px; font-weight: 600; line-height: 1.2; font-family: freight-sans-pro, sans-serif; -webkit-font-smoothing: antialiased; text-rendering: optimizelegibility; color: rgb(46, 46, 46);\">Soraya Calavassy, communications manager at the Award in Australia,&nbsp;shares her organisation&#39;s experience&nbsp;piloting our new global visual identity.</h3>\r\n\r\n<p style=\"margin: 0.5em 0px 0px; text-rendering: optimizelegibility; font-size: 1.30769em; line-height: 1.3; color: rgb(78, 78, 78); font-family: freight-sans-pro, sans-serif;\">&quot;While Australia has a very strong brand locally, there are some great benefits for incorporating"

When displaying the post i use raw which does give me the output I need. But I need to generate an excerpt. For that, I need to strip all the HTML tags and even remove the images. But when I use sanitize it won't remove the images. If I use strip_tags , it will remove the images but it will add ' for apostrophe,   for space, etc. So, how to get a clean excerpt without images and without   stuff?

Answer 1

try strip_tags(text).html_safe

Answer 2

Doesn't work with rails 4.1

Only way by combing strip_tags with the gsub function (link below)

Ruby gsub multiple characters in string

So in helper, I'd do:

def format_text(string)
    strip_tags(string).gsub(" ", "").gsub("'", "'")
end
