I've been walking around for hours and I can't seem to get it. I seem to be able to down the grove easy enough (process-first-descendant, (select-elements (children (current-node), etc. but I can't seem to go up. I'm gonna bug you for more help. I hope you don't mind. I have this partial doc instance ... <IXML> <HEAD> <DESCRIPTION><TITLE>THE TITLE</TITLE></DESCRIPTION> </HEAD> <BODY> ...</BODY> I've tried a bunch of different examples and I won't bore you with the broken code. But the key is probably understanding what this does (define (get-publisher-name node) (let ((gr (node-property 'grove-root node))) ; do navigation magic here )) what does "gr" mean here. I tried sticking that inside (parent (gr)) thinking it was a node but it is not because that doesn't seem to work. I've also tried working with (node) but that hasn't got me above the level of <BODY> Are you selecting the ROOT element here? (which in my DTD would be IXML?) If I pass <BODY> as current node like (element BODY left-header: (get-publisher-name (current-node)) where do I start from? can I also (element BODY left-header: (get-publisher-name (parent (current-node))) sorry to bug you. thanks for all your help mike DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
