[opencms-dev] XML Content Demo

[Jonathan Woods]

I agree with Christian - without heavy customisation, there's no way to use
the existing XML editing framework to do what you suggest.  There was talk
some while ago of re-implementing the XML editing framework to use a nice
AJAX framework, but nothing has yet come of it.

Concerning your question about combo box values: as you probably know,
they're usually retrieved from a properties file named in the XSD:

<xsd:annotation>
		<xsd:appinfo>
			<resourcebundle
name="{{runtime.opencms.module.name}}.workplace"/>

Actually, they're resolved through the usual Java properties mechanism, so
instead of providing a fully qualified Java class which actually maps to a
file (workplace.properties here), you could provide a fully qualified Java
class name which maps to... a Java class of your own which extends
java.util.ResourceBundle.  That Java class could get its values from
wherever you like.  Warning: I think OpenCms caches property values thus
obtained, so you might find you need to reload the module, or even restart
OpenCms, for new values to be picked up.  Come to think of it, though, there
is a Workplace function to 'reload the Workplace' - that might also flush
property caches, and you may even be able to hook into that
programmatically.

AFAIK, regular expressions are only meant for checking the format of an
individual field.
Sadly I don't know if there is a way to perform more complicated checks.

I think you would have to digg around - maybe you can extend the generic XML
resource type class so that it can do what you need.
