copied!<p>This appears to be issue with what Nokogiri expects as parameters to the parse method that is being called. The first issue I see, is that you are passing in the encoding option in the wrong parameter slot,</p> <p>A <a href="http://nokogiri.org/tutorials/parsing_an_html_xml_document.html" rel="nofollow">parsing example</a> from Nokogiri project page that specifies encoding</p> <pre><code>Nokogiri.XML('<foo><bar /><foo>', nil, 'EUC-JP') </code></pre> <p>Notice the encoding is the third parameter, not the second. But that still does not fully explain the behavior you are seeing, as the encoding should simply be ignored.</p> <p>Per the Nokogiri documentation a call to Nokogiri::HTML() is a convenience method for the parse method.</p> <p>Code for Nokogiri::HTML::parse</p> <pre><code> def parse thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_HTML, &block document.parse(thing, url, encoding, options, &block) end </code></pre> <p>The <a href="http://nokogiri.org/Nokogiri/HTML/Document.html" rel="nofollow">source</a> for the Nokogiri::HTML::Document parse method is a bit long, but here is the relevant part though:</p> <pre><code> string_or_io.respond_to?(:encoding) unless string_or_io.encoding.name == "ASCII-8BIT" encoding ||= string_or_io.encoding.name end end </code></pre> <p>Notice <strong>string_or_io.encoding.name</strong>, this matches the error your saw, <strong>undefined method 'name' for "UTF-8":String (NoMethodError)</strong>. </p> <p>Does your search_results object has an attribute with a key value pair of {:encoding => 'UTF-8'}? It appears Nokogiri is looking for the encoding to store an object that then has a name attribute of 'UTF-8'.</p>
