XML Schema Validation in CF?

Does anyone know of a way to validate xml in CF against an XML Schema other than WDDX?

I believe strongly that it can't be done with native CF tags/functions, but perhaps there's an (open source) solution somewhere? I'm sure I'm not the first person to have this problem.

Thanks in advance.

This can be done using the underlying Java API classes. This function validates an XML document against a DTD. I would assume that modifying it to validate against a schema would not be too difficult.

I'll give that a try - unfortunately I'm stuck with CF 4.5, so I can't confirm or deny that I'll have access to the Java API. Thanks.

If I get it working with schemas rather than DTD I'll definately post a followup.

Unfortunately, you won't be able to do anything like this with CF 4.5. You'd need CFMX to call the Java API classes since CFMX is Java-based. My only advice for trying to do this with 4.5 is search for some custom tags, CFX tags, COM, or CORBA components that might do XML validation. You might start here: http://www.cfdev.com/xml/xmlparser/ or here http://www.granularity.net/technologies/

Also, you're probably fully aware, but doing something like this is way, way easier with CFMX than 4.5. CFMX has built-in support for XML, web services, and just about everything else. Good luck.
