 Karen, The xt:node-set function converts a result tree fragment into a nodeset while you tell us that your Java function returns a string.... If (as I'd guess) this string contains tagged contain, you cannot convert it into a nodeset... Instead, your function should return a "ResultTreeFragment" meaning that it should implement the XT ResultTreeFragment interface. This interface is quite easy to implement (it's a SAX parser...) and I have written some documentation about it on 4xt: http://4xt.org/docs/000421-0001.xml Hope this helps.
