I think the essential point is that when you've got a language that fits its data model, you're happy, and when you're using a language that doesn't fit it's data model, you're forever cutting against the grain. The famous impedance mismatch. XSLT and XQuery are very closely designed around the XML data model with all its peculiar quirks; that makes them very good at doing XML, and a bit of a peculiar choice for doing anything else. Designing a data model that can embrace XML and JSON with a high level of fidelity is not easy, as we are finding - it's easy to find you've designed a camel (or a chimera in Jeni's memorable terms).
No-one in my view has ever really succeeded in designing a data model that works well for integrating heterogeneous data sources. They've been trying for at least 40 years. My own preferred candidate is the functional data model, because it so minimalist, but it's not exactly a fashionable candidate right now.
