Thank you for the reply Alain.
It will be interesting times when 'fleur' and XSLTForms 2 arrive. :-)
For now, as I said, I am wanting to generate a xsd:duration content based
on a start and end xsd:date and xsd:time elements entered via a xform.
I have not got far enough yet to submit a working xform test case skeleton,
as I am just trying to sort out the best way to generate the xsd:duration,
however for instance:
...
<datestart>20160510</datestart>
<timestart>083000</timestart>
<dateend>20160511</dateend>
<timeend>104500</timeend>
<duration>PT26H15M</duration> <------- calculate this, a duration
showing hours and minutes, from the date and time elements
...
What would be the best and/or efficient approach please?
At the moment I am intending to use xf:bind calculations, using substring,
floor and div functions etc on the date and time elements, to
*eventually* get the desired content for the xsd:duration element.
Perhaps there is a better approach ?
As an aside, if I have understood it properly, the EXSLT template
'date:duration' provides this process, so perhaps it is possible to do a
xslt transform within XSLTForms to produce the desired duration instance.
I will keep on it and see what I come up with, but if you (or any one else)
have any ideas/tips please let me know.
Regards
Habs
