If you give up on installing a newer version of libxml (I've tried it in
the past and found it impossible), you can use xpath() to do what you
want:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<h1 class='editor highlight'>Hello world</h1>
<div class="editor_fruit red">Apple</div>
<div class="article_editor">
<div>Not this node</div>
<div class="hide editor">Papillon</div>
</div>
</body>
</html>
require 'nokogiri'
f = File.open('2html.htm')
doc = Nokogiri::HTML(f)
results = doc.xpath("//*[contains(concat(' ', @class, ' '), ' editor
')]").each do |el|
p [
el.attributes['class'].value,
el.children[0].text
]
end
--output:--
["editor highlight", "Hello world"]
["hide editor", "Papillon"]
