Nokogiri::XML::NodeSet#to_xhtml adds invalid CDATA tags

[JonCrawford]

Run the following gist: https://gist.github.com/f1ec33937642648a78cb

Notice the <![CDATA[ ]]> tag that is created inside the <style> tag. This is bad because CDATA tags inside <style> tags require CSS comments around them or they have they cause the CSS to not be parsed by the browser.

Info here about CDATA tags: http://en.wikipedia.org/wiki/CDATA#Use_of_CDATA_in_program_output

Fixies?

I need to rewrite this example in C and supply it to the libxml2 team. I suspect this is a bug in libxml2.

[JonCrawford]

Bump.

Ran the gist with libxml2 2.6.16 and didn't get any CDATA tags so, yeah, looks like a libxml bug.

Same problem with master and ubuntu 10.10

Confirmed bug still present upstream in libxml 2.9.4.

I believe this behavior was introduced in libxml 2.6.31 in GNOME/libxml2@dbd6105 and appears to be intentional. Closing.
