You can return node sets, but for this requirement wouldn't it be simpler to
return a sequence of strings?
Are you asking about the reflexive extension functions in 9.1, or the new
integrated extension functions in 9.2? With the new mechanism, it's all very
straightforward as everything is strongly typed and you have to return
values of the Saxon-defined types such as XdmNode and XdmAtomicValue. With
the older mechanism, Saxon tries to recognize whatever object you return -
the rules are at

Subject: [saxon] extension functions returning node sets
Using the .NET version of Saxon, is it possible to return a node set from an
The only alternative I've figured out to do it so far is to return a
delimited string which I then tokenize, but I'm wondering if there are
better techniques (because if I ever change my extension function to, for
example, change the columns of data I'm fetching, I have to .
To give an idea of what I'm doing, I'm querying a database. Unfortunately,
the Saxon database extension isn't available in .NET. So, my extension
function queries a database and returns the values of multiple columns in
the database. I'm looking for a nice clean way to do that.
