Is it feasible to use XML Schemas to validate data entry forms? For example, I have an XSLT stylesheet that creates an HTML input form. The user fills out the form, clicks submit, but then my program needs to validate the data. One solution would be simply to convert the POST data into a simple XML doc and have a corresponding schema that defines many validations. This way, I wouldn't have to define regex/min/max/etc in the validation bean, I could just pass it to the schema-based checker. Then I could return the XML data with the linked schema back to the web browser for subsequent display.
Is this really possible? Can XML Schema tell me WHICH field(s) are invalid so that I could display an error message back to the user and flag that field so the user would know which field was in error and why? Or do I have to wait for XFORMS to be viable to do this sort of thing? Thanks, David
