Using a regex pattern in an XForm

John Boyer

This is an FYI:  You can use the "type" model item property to validate a data node with a regex pattern expression, like this:

<xforms:model>
   <schema targetNamespace="http://test.org" xmlns="http://www.w3.org/2001/XMLSchema">
      <simpleType name="alnum">
         <restriction base="xsd:string">
            <pattern value="[A-Za-z0-9]*"></pattern>
         </restriction>
      </simpleType>
   </schema>
   <xforms:instance xmlns="http://test.org">
      <data>
         <node></node>
      </data>
   </xforms:instance>
   <xforms:bind nodeset="test:node" type="test:alnum"/>
</xforms:model>

Cheers,
