trying to get content inside cdata tags in xml file using nokogiri

Solution
You're trying to parse XML using Nokogiri's HMTL parser. If `node` as from the XML parser then `r` would be `nil` since XML is case sensitive; your `r` is not `nil` so you're using the HTML parser which is case insensitive.
Use Nokogiri's XML parser and you will get things like this:
>> r = doc.at_xpath('.//NewsLineText')
=> #<Nokogiri::XML::Element:0x8066ad34 name="NewsLineText" children=[#<Nokogiri::XML::Text:0x8066aac8 "\n ">, #<Nokogiri::XML::CDATA:0x8066a9c4 "\n Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly creme brulee.\n ">, #<Nokogiri::XML::Text:0x8066a8d4 "\n">]>
>> r.text
=> "\n \n Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly creme brulee.\n \n"
and you'll be able to get at the CDATA through `r.text` or `r.children`.
Problem
I have seen several things on this, but nothing has seemed to work so far. I am parsing an xml via a url using nokogiri on rails 3 ruby 1.9.2. A snippet of the xml looks like this: ``` <NewsLineText> <![CDATA[ Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly creme brulee. ]]> </NewsLineText> ``` I am trying to parse this out to get the text associated with the NewsLineText ``` r = node.at_xpath('.//newslinetext') if node.at_xpath('.//newslinetext') s = node.at_xpath('.//newslinetext').text if node.at_xpath('.//newslinetext') t = node.at_xpath('.//newslinetext').content if node.at_xpath('.//newslinetext') puts r puts s ? if s.blank? 'NOTHING' : s puts t ? if t.blank? 'NOTHING' : t ``` What I get in return is ``` <newslinetext></newslinetext> NOTHING NOTHING ``` So I know my tags are named/spelled correctly to get at the newslinetext data, but the cdata text never shows up. What do I need to do with nokogiri to get this text?
