That sounds like a bug to me, I think it should simply return an empty node set. >I think that setting a variable via the content = result tree fragment >should be something like <xsl:copy-of select="document(/R/L/@uri)"/> >but it doesn't work. > That should work, with one caveat: remember that count(node-set($refxml)) will *always* be 1, regardless of how many input documents you have. Your original attempt will give you a node set containing a root node for each document (two in the example you gave). Because the copy-of doesn't copy the root nodes returned by the document call, you will get (after calling node-set($refxml)) a node set with *one* root node whose children are all the top level nodes from the documents read. Maybe this is tripping you up later? Also the 'otherwise' might as well be empty: you cannot stop the root node for the result tree being created by doing anything here with empty node-set. Note, <xsl:value-of select="/.." /> gives you a text node containing an empty string. You 'copy' an empty node set by doing nothing!
