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

Question

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 xm

Answer 1

Ah I see. What @mu said is correct. But to get at the cdata directly, maybe:

xml =<<EOF
<NewsLineText>
  <![CDATA[
  Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly     creme brulee.
  ]]>
</NewsLineText>
EOF
node = Nokogiri::XML xml
cdata = node.search('NewsLineText').children.find{|e| e.cdata?}

Answer 2

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.
