thanx for your help, James. holy mackrel! that's exactly what I'm trying to do. Create a master xml = doc (data island) and then add nodes (copy) to it from the = xmlhttprequest xml doc. the xmlhttprequest *has* to be there - it's providing lookup data that = gets displayed in a form for editing (think remote procedure calls). As each lookup happens I have to store the previous changes somewhere = (the master doc?) and then post that as one hidden field back to the = server for processing. The master doc basically provides a new root node = and some id attributes, ready to be filled with child nodes from the = xmlhttprequest doc. I've been beating my head against the wall trying to get this to work. = It never occured to me that they'd be two incompatable xml objects. looks like I've been tricked into thinking this could work because I can = use some JS functions to manip the xmlhttpreqest doc already (to display = in form elements or post back to the server, yes, but not copy or = clone). now I'm really stuck. any ideas on how I can aggrigate the results of = each lookup (ie: add nodes) to send back to the server in one hidden = form field? looks like the data island idea won't work.... (in panic mode) I'm thinking that, since there's form elements involved, = I might get away with creating xml nodes on the fly and just copying the = data and attribute values (up to 4 per child node). I've had to do = something similar serverside with ColdFusion - java didn't want to play = nice (eg like this: = http://www.spike.org.uk/blog/index.cfm?do=3Dblog.day&day=3D4&month=3D6&ye= ar=3D2004) any suggestions are most appreciated worried... barry.b -----Original Message----- From: xml...@li... on behalf of James S. = Elkins Sent: Wed 8/12/2004 12:50 AM To: xml...@li... Cc:=09 Subject: [xmljs-users] Re: xmljs-users digest, Vol 1 #50 - 2 msgs Barry, Do I understand you correctly as saying that you're creating the first = DOM=20 in <XML for Script> and the second DOM using the browser's native=20 XmlHttpRequest object? If so, you can't copy nodes from one to the other = because one is a JavaScript object and the other is an ActiveX or = Mozilla=20 object. The standard DOM methods may be the same, but the interfaces are = implemented differently.
