How to strip html tags out of xml generated by builder in rails
Here is my situation. I'm trying to create a valid rss feed for an itunes podcast from an existing project. It's a rails application that allows uploading of mp3 radio shows to for listening on the site. I want to take all entries in the database and create an rss feed out of it. I'm using a builder file and everything is working fine. I noticed though that there's html tags stored in the database from a text editor. for example strong tags and span tags are getting put inside of my xml whe开发者_Python百科n the feed is output. Is there a way to strip that stuff out in the controller or in the xml builder?
My controller:
class PodcastsController < ApplicationController
def index
@podcasts = Event.find(:all, :order => "date DESC", :conditions => ['radio = ?', 1])
respond_to do |format|
format.xml
end
end
end
If the tags are very simple, you could just use a regular expression to strip them out. For example:
"<html>Hello <b>world</b>.</html>".gsub(/<.+?>/, '')
=> "Hello world."
If it's more complex than that, it might make sense to load it in nokogiri and extract the text nodes.
