It would be helpful if you could be more explicit about the FROM
database.

Relational purists will argue there has never been an implementation of
a relational DBMS. So it's probably best to consider SQL databases, but
there's a bifurcation of the SQL DBMS world:

1. Some SQL platforms do not support an XML data type so it's necessary
to shred an XML document or store it as a CLOB column (with the XML in
its native format).
2. Other SQL products have implemented an XML data type and/or a hybrid
storage engine that stores XML in its native format.

The switch getting the most publicity these days is from SQL platforms
to distributed key-value stores, not to XML data stores.
