RE: [flexcoders] Validating XML with XSD Schema in Flex?
Where is the XML coming from? Can you use server-side code to validate the XML before sending it to Flex? That's probably the simpler solution.

I've been scouring the web tyring to find information on XML validation using an XSD file, but the only results I keep finding relate to the MXML schema which is not what I'm looking for. Has anyone written any code that validates an XML file against it's schema? Or is this of of the coding practices that Flex does not implement? The point being, if I want to explicity define what my input XML looks like to my flex application, right now, the only way this seems possible to to write code that defines the business logic of each node/attribute and whether or not there is a value restrition. Should my business logic change, then I have to go and change my code. If there is some way to simply read the XSD and validate directly against that, the only place I have to go to change my business logic is to the XSD--no code changes/recompilations necessary.

RE: [flexcoders] Validating XML
All that is possible in Flex is based on the Flash Players capabilities. Validation with XSD is not implemented in the player and thus not possible in Flex. The flash player only has most basic features available, as u know its only possible to dynamicly load one type of image, sound and movie. This is don't in order to keep the player itself small. I guess the same reason has made that XSD didn't make it into the player.

Furthermore, the use of XSD's for data objects allows the proliferation of many standard value objects to be used across a myriad of applications with the ability of those applciations to validate the data they are sending, thus ensuring ease of communication across disparate systems. With the above 2 said, that is my guess as to why someone would expect Flex to validate the XML via the XSD before sending; that way you can ensure the data you are sending back to Java is valid ... in form, not in contents. So, if the number is 0-0-0-0-0 instead of 000-000-, that is a data input validation error, but at least the data is well formed. Does that make sense? I'm not saying I agree with using an XSD vs. just straight RemoteObject and mapping both server-side and client side value object classes to match as close as possible, and through testing you are ensured that the data works since you mirrored the Java class client side in a value object, but your thoughts do help me understand the why someone would want to do it; I'm trying to build up a decent inference here.

Quick answer is no, I don't think you can do schema validation on the client ... however, I'd also argue that this kind of validation belongs on the server anyway (and that client-side validation exists to improve the user-experience, and to reduce unncecessary roundtrip to the server, rather than to validate correctness of the data in the strictest sense).
