XPath does not give you a way to do this.

Here's what CDATA sections do, according to the XML Rec:

So in XQuery, the purpose of a computed CDATA constructor would be to 
escape text that contains characters which would otherwise be recognized as 
markup. Once you get these characters past the parser, they are just 
characters, and the XPath data model does not preserve the boundaries of a 
CDATA section (nor does the XML Information Set).
