nokogiri

I am trying to parse Youtube Gdata to see if video with given id exists. But there isn't normal tag but with namespace. On the link http://gdata.youtube.com/feeds/api/videos?q=KgfdlZuVz7I there is tag: <openSearch:totalResults>1</openSearch:totalResults> There is namespace openSearch: xmlns:openSearch='http://a9.com/-/spec/opensearchrss/1.0/' but I dont know how to deal with it in Nokogiri and Ruby. Here is part of code: xmlfeed = Nokogiri::HTML(open("http://gdata.youtube.com/feeds/api/videos?q=#{video_id}")) xmlfeed.at_xpath("openSearch:totalResults") It gives error: Undefined namespace

How can I use Nokogiri with having html entities (like German umlauts) untouched? I.e.: # this is fine node = Nokogiri::HTML.fragment('<p>ö</p>') node.to_s # => '<p>ö</p>' # this is not node = Nokogiri::HTML.fragment('<p>ö</p>') node.to_s # => '<p>ö</p>' # this is what I need node = Nokogiri::HTML.fragment('<p>ö</p>') node.to_s # => '<p>ö</p>' I've tried to mess with both PARSE_OPTIONS and :save_with options but could not come up with a way to have Nokogiri just transparently behave like above. Any pointers? svenfuchs Ok, my question has been answered by Aaron via twitter / gist : require

I'm using nokogiri to select the 'keywords' attribute like this: puts page.parser.xpath("//meta[@name='keywords']").to_html One of the pages I'm working with has the keywords label with a capital "K" which has motivated me to make the query case insensitive. <meta name="keywords"> AND <meta name="Keywords"> So, my question is: What is the best way to make a nokogiri selection case insensitive? EDIT Tomalak's suggestion below works great for this specific problem. I'd like to also use this example to help understand nokogiri better though and have a couple issues that I'm wondering about and

I have a simple task of accessing the values of some attributes. This is a simple script that uses Nokogiri::XML::Builder to create a simple XML doc. require 'nokogiri' builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml| xml.Placement(:messageId => "392847-039820-938777", :system => "MOD", :version => "2.0") { xml.objects { xml.object(:myattribute => "99", :anotherattrib => "333") xml.nextobject_ '9387toot' xml.Entertainment "Last Man Standing" } } end puts builder.to_xml puts builder.root.attributes["messageId"] The results are: <?xml version="1.0" encoding="UTF-8"?>
