Hi Markus,
try
for $title in collection('edil_target/eDIL-A.xml')//entry//title where not($title/@target = $biblStruct) and not($title/@target = $biblFull) return $title
Thank you for the quick reply at such a late hour! However, I am getting the same results sadly. These results I can open the files and find the targets that are being return in either of the two lists.
All the best, Chris
