Helen, I'm not sure this will make a difference, but try these alternatives:
fn:base-uri(doc()/ns1:article//ns1:sub[not(@temp1 or @temp2)]) fn:document-uri(doc()[ns1:article//ns1:sub[not(@temp1 or @temp2)]]) I'm not sure (internally) how this usage differs from the other, so it may or may not work. In the document-uri case, I made a change to the XPath to avoid having to use root function, but you can try either way.

Now I understand why sometimes when I use document-uri() and it returns empty sequence, that's because it is not document element. So I did the following test: ------------- for $doc in doc()/ns1:article//ns1:sub[not(@temp1 or @temp2)] let $uri := try { base-uri($doc) } catch ($e) { () } where not($uri) return $doc it returns empty sequence ----------------------- for $i in doc()/ns1:article//ns1:sub[not(@temp1 or @temp2)] return base-uri($i) it returns 7 uris and they are actually the same uri (/pt/ajr_1.xml), just because there are 7 ns1:sub nodes found. ------------------ when I tried to run doc()/ns1:article//ns1:sub[not(@temp1 or @temp2)]/fn:base-uri(.) I got error : Description: XDMP-NOTANODE: doc()/child::ns1:article/ descendant::ns1:sub[attribute::temp1 or attribute::temp2]/base-uri(.) -- xs:anyURI("/pt/ajr_1.xml") is not a node the base-rui() function returns type anyURI, not a node, is this what it complains?
