The use of InfoPath avoids the end user generating XML data files in full handwriting, as well as unifying XML file formats that are widely used in MOSS systems and Web site development. Using InfoPath to develop an XML front-end form page requires several specific steps, such as writing an XML sample file, generating an XML schema file, importing the main data source in InfoPath, designing an InfoPath form rendering, and adding a C # event code to the form if necessary. such as the action to

A core feature of the Bean Validation (JSR 303)--java EE 6, which defines a metadata model and API for entity validation. Its default metadata source is annotations, but developers can extend it through an XML descriptor. The Validation API does not rely on a particular application layer or programming model, so that the same set of validations can be shared by a
