RE: [xsl] Ways to simplify XSL, complex "select/filter criteria"

[J L <jinlii@xxxxxxxxxxx>]

I tried the transformation in Altova. It complains about Error in XPath 2.0
expression
Cast failed, invalid lexical value - '2005-09-19T00:00:00
                 ...

             ...
2010-09-19T00:00:00email1@xxxxxxxxxxxxxxxxxxx:00:00email2@xxxxxx'

If I change '2005-09-19T00:00:00' to 2005-09-19. The same error. Do you know
why?
