Hi Pierre,

I think the problem lies within your bind-expression, or the "type" attribute to be mor precise.
You defined a namespace "http://www.w3.org/1999/XMLSchema" with the prefix "xsd", but within your type 
attribute you are using an "xs" prefix.

Your bind should read:
<xforms:bind id="bind_1" nodeset="instance('instance_0')/champ1" type="xsd:integer" constraint="string-length()=2" required="true()"/>

BTW, I don't think it is necessary to qualify your id and bind attributes.

Betreff: Xforms Validation


  I've been trying in vain to add constraints to a xforms. What I am trying to do is to make sure the user will enter an integer in a certain field. I found easy to test the length of a field or others things using Xpath functions, but I dont see how I can test the type or how I can use regular expressions. 
  In the code below, the user can enter a 2 characters string, even if the type is an integer. How can I prevent the user from entering anything else than numbers ?

PS: By the way, I think Xforms is the "next big thing". Or I'll be damned to try to understand how it works for nothing !!
