How can I count all the distinct timezones in a single XML document using
I have an XML document with many elements and attributes with the type
xs:date or xs:datetime. One of the rules of the system receiving my document
is that all timezones must be the same in the document. Ideally I would like
to express this constraint purely in XPath 2 rather than XQuery so I can put
the constraint in a xs:assert statement.
If there was a map function in XPath I would write something like this:
xs:date)|attribute(*, xs:date)|element(*, xs:datetime)|attribute(*,
xs:datetime))))) eq 1
This XPath would return true if all timezones were the same, and false
However there is no map function in XPath, so how can I achieve the same
thing without it? What is the nearest I could get.
