Hm, so would you expect the findnodes_as_string() return value in your example include the CDATA markup then? sdlfkkskdfjl <![CDATA[cdata grind <hallo> sdsdfsdf]] As I understand this, that's the other option available. In particular, returning unquoted text like findvalue() does would not be "reproducing the node as XML."

My thinking was that the return value is not text "within a CDATA section", but rather (more or less) standalone XML, so this wouldn't apply. I always thought CDATA sections are just a way of escaping the inconvenient characters in input, and not sacrosanct entities that must stay untouched. How absolute is this? If an XML filter gets input like <![CDATA[<test> string]] and outputs <![CDATA[<test>]] string is it doing the wrong thing? > >I'm thus closing the bug.
