Parsing Atom & RSS in Ruby/Rails?

Question

i'm using the nouislider (http://refreshless.com/nouislider/) with some buttons to get the slider controlled via the buttons and with an active status on the buttons for the picked value.

in modern browsers, like firefox, safari, chrome and ie10 the script works good i think. but in the shitty ie 8 this piece of code acts pretty strange: the wrong buttons are marked as active and all of the: "please add the class to the right buttons" doesn't work.

this is the function for the active status:

    function headClassToggle() {

        $('#calc-heads button').removeClass('calc-active');
        $('#calc-heads #calc-1').addClass('calc-active');

        var calcSliderValue = $('#calc-slider').val();
        var iEra = $('#calc-heads button');
        var thumbLi = $('#calc-heads button');

        for (iEra = 1; iEra < calcSliderValue; iEra++) {
            thumbLi.eq(iEra).addClass('calc-active');
        }
    }

here you can find a working example:

so my question, what could be wrong on the for loop for internet explorer 8?

thanks!

Feedzirra is one of the better options: http://www.pauldix.net/2009/02/feedzirra-a-ruby-feed-library-built-for-speed.html

Of course, I'm biased since I wrote it. :)

Googleage reveals some things. Were they not acceptable?

Simple RSS
Ruby-Feedparser

require 'simple-rss'
require 'open-uri'
rss = SimpleRSS.parse open('http://slashdot.org/index.rdf')
rss.channel.title # => "Slashdot"

If you meet crappy feeds, you may want to use HPricot to parse the feed.

Solution 4

Feed Normalizer looks like it may be a good option

Looks like in 2009 the standart Ruby RSS library just didn't exist yet?
