Re: [xml-dev] XML Schema 1.1 xpath 2.0 regex question

Validation should succeed.

With the "m" flag, it's valid, because there is a line that matches ^hello$ (and as it happens, there is also a line that matches ^world$, but that match is not needed). One match is sufficient.

Hi all,

   I've following XML instance document,

<?xml version="1.0"?>
<X>
  <a>
hello
world
  </a>
</X>

And the following XML Schema 1.1 document,

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:element name="X">
       <xs:complexType>
          <xs:sequence>
             <xs:element name="a" type="xs:string"/>
          </xs:sequence>
          <xs:assert test="matches(a, '^(hello|world)$', 'm')"/>                                          
       </xs:complexType>
    </xs:element>

</xs:schema>

When I validate the, XML instance document that's provided with the provided XSD 1.1 document, I get a valid outcome. Shouldn't the XSD validity outcome be invalid? It think so, because the string content of element "a" after 'world' (within XML instance document) is not either hello or world (as specified by regex within the XSD document).

Any thoughts would be helpful.
