It's the one I've tried, without success.

Best, Tom.

Hi !

I'm not a regex killer, especially when regex flavour is not the one
I
use on my linux box...

In a schema, I need a simple type that allows a QName, written
either
"prefix:localName" or in ClarkeForm "Q{nsUri}localName", or in
the-last-one-I-cant-remember-the-name "{nsUri}localName"

I've started with the one available in XSD schema :

<xs:simpleType name="QName">
<xs:annotation>
<xs:documentation> A QName. This schema does not use the
built-in
type xs:QName, but rather defines its own QName type. Although
xs:QName
would define the correct validation on these attributes, a schema
processor would expand unprefixed QNames incorrectly when
constructing
the PSVI, because (as defined in XML Schema errata) an unprefixed
xs:QName is assumed to be in the default namespace, which is not the
correct assumption for XSLT. The data type is defined as a
restriction
of the built-in type Name, restricted so that it can only contain
one
colon which must not be the first or last character. TODO: change
implementation to allow use ClarkeForm </xs:documentation>
</xs:annotation>
<xs:restriction base="xs:Name">
<xs:pattern value="([^:]+:)?[^:]+"/>
</xs:restriction>
</xs:simpleType>

But my pattern for ClarkeForm isn't correct :
<xs:pattern value="Q?\{[^\{]+\}[^:\{\}]+"/>

Any help will be appreciated.
Thanks in advance,
Christophe
