trying to get content inside cdata tags in xml file using nokogiri
Solution 1
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
.
Solution 2
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?}

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?

Aaron Thomas about 12 yearsBah.. I was using HTML and tried to be case sensitive and it wasn't giving me any results and I couldn't figure out why so I dropped it all to lowercase which worked. Later I tried using Nokogiri's XML parser, but I did it ignoring case and it returned no results. I suppose I should have tried XML and case-sensitive and it would have worked with what I was trying. I will check this out and let you know the results.

Aaron Thomas about 12 yearsYou were all correct. I was unintentionally using the HTML parser which forced me to use lowercase. Then when I tried to use the XML parser, I got no results(because I was already using lowercase). After seeing the answers here, I realized my idiocy and switched to case sensitivity and XML. Works perfect. thanks
