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(_at_)my(_dot_)com2010-09-19T00:00:00email2(_at_)my(_dot_)com'
If I change '2005-09-19T00:00:00' to 2005-09-19. The same error. Do you know
why?

I don't think I fully understand the requirement, but it's certainly a case
where your code can be simplified by use of functions. For example you can
define this function
select="xs:dateTime($v/ns:startDateTime)"/>
select="xs:dateTime($v/ns:endDateTime)"/>
and this one
and then you can do things like
[exists(ns:validFor[f:applies-now(.)])]"/>

Subject: [xsl] Ways to simplify XSL, complex "select/filter criteria"
Hi all,
first my environment: Saxon 8.9, XSL and Xpath 2.0, Java
I have to transform a XML document which contains elements
with the same name but different xs:type.
In addition the elements contain an optional validFor element
which defines a time period for the validity of the data.
The rules to implement is:
- select element by xsi type
- select the valid (in time period) element
- if no time period specified and multiple elements of the
same type exist, take the first one
I have to apply these rules in almost every value-of
selection in my XSLT and therefore the XSLT became really a nightmare.
I hope there is a solution to simplify this. I though about
xsl:function, dynamic Xpath (saxon:evaluate,..) but couldn't
get it to work.
Any help more than appreciated!
Thanks
Stefan
