RE: Against the Grain: Pascal commentary about XML and databases

Relational databases won over the faster but less powerful (due to the lack of
arbitrary joins) hierarchical databases in Days Of Old, mainly due to data
modelling issues IIRC.

Does anyone know how/if XML databases differ from those old relational database
revisited, and if the arguments then still hold? Any historical recordings of
those debates?
