Remember, the moment you convert back into an individual node you lose the capability to go back up the tree. So the descendants are actually zippers, with the root of each zipper set to a descendant node. Because you're using xml1-> and not xml->, you only get the first result of the seq. This is why it looks like it just returns the original zipper, but it actually returns the first descendent zipper. If you want to get a list of all the descendants as nodes, you need to use xml->, and put clojure.zip/node on the end: (dzx/xml-> my-zipper dz/descendants z/node) > (dzx/xml1-> my-zipper :html) > > returns *nil*, which I *really *wasn't expecting.

So you're looking for a html tag inside a html tag. These should return non-nil values: (dzx/xml1-> my-zipper :head) (dzx/xml1-> my-zipper :body) If you want to find your input: (dzx/xml1-> my-zipper :body :input z/node) Or to do a descendant search: (dzx/xml1-> my-zipper dz/descendants :input z/node) - James -- You received this message because you are subscribed to the Google Groups "Clojure" group.
