How do I get a Node element from a Nokogiri::XML::Reader?

The docs state that you can loop through the nodes with .each, and a node will be returned to the block. However, this is not true. The \"node\" that is returned is just an instance of Reader.

I need to get the Node object so that I can access the:

node.content

However, this appears to be poorly documented. At any rate, I can't开发者_JAVA百科 find out how to do something so simple after 2 hours of trying. Any help is appreciated.


Are you looking for something like this?

require 'nokogiri'

xml = <<eoxml
<x xmlns:tenderlove='http://tenderlovemaking.com/'>
<tenderlove:foo awesome='true'>snuggles!</tenderlove:foo>
<truth>echo chamber</truth>
</x>
eoxml

doc = Nokogiri::XML::Reader(xml)

doc.each do |node|
  if node.attributes == {"awesome"=>"true"}
    puts node.inner_xml
  end
end

# => snuggles!
