Subject: Re: [xsl] strong typed variable with restriction ? From: Matthieu Ricaud-Dussarget <matthieu.ricaud@xxxxxxxxx> Date: Wed, 02 Feb 2011 19:59:01 +0100 |
Sorry Michael, this mails stayed as draft, I've just seen that... so a bit out of ..."hour"
No, that won't solve the problem. If the declared type of the function is element(), then the otherwise branch (whether explicit or implicit, whether executed or not) must return an element.Yes I know that. It's not the best solution but when turning the function to element()* then it will be a way of simulating the "typed param" error instead of the processor.
(I didn't know that point for java, but I knew it for xslt ;-) i'm a xslt developper more than any langage actually)
(It's not like Java, where you can declare a function to return String, and still return null. If you want to allow a "null" return in XSLT, you need to declare the result as "xs:string?").
