The logical structure is the hierarchy of elements, starting with the
document element at the top with nested elements below until you get to
elements that do not have any child elements.
The physical structure is the hierarchy of entities (files, web resources,
etc.) in which you store or obtain your XML markup, starting with the
document being parsed, including nested external parsed entities that are
referenced by the document being parsed.
Each physical entity must have a well-formed logical structure, therefore,
the end result of pulling in the nested physical hierarchy results in a
well-formed logical structure for the document as a whole.
I hope this helps.
