public class: Validation [javadoc | source]
A sample to illustrate two means for validating XML against schema using features of the XMLBeans API. The features illustrated are: - Validating after changes by using the XmlObject.validate method. This method is exposed by types generated by compiling schema. The validate method validates instances against all aspects of schema. Also, with this method you can specify a Collection instance to capture errors that occur during validation. - Validating "on the fly" using the XmlOptions.VALIDATE_ON_SET constant. This option prompts XMLBeans to validate XML against simple schema types as you set them, rather than by expressly calling for validation. You can set this option by calling XmlOptions.setValidateOnSet, then specifying the XmlOptions instance as a parameter when creating a new instance from schema or parsing an existing one. Note that it is also possible to validate instances from the command line by using tools you'll find in the bin directory of the XMLBeans distribution.

Method from org.apache.xmlbeans.samples.validation.Validation Detail:
 public boolean isValidAfterChanges(String xmlPath) 
    Illustrates use of the validate method by making changes to incoming XML that invalidate the XML, then validating the instance and printing resulting error messages. Because this code is designed to generate invalid XML, it returns false when successful.
 public boolean isValidOnTheFly(String xmlPath) 
    Illustrates the "validate on set" feature, which validates XML for simple types on the fly. As XML for those types is "set" through accessors generated by compiling schema, XMLBeans checks the XML's validity. The code here uses generated types to retrieve the first in a , then update the 's id attribute. The code throws an exception when it tries to set an id attribute value that is too high. Because this code is designed to generate invalid XML, it returns false when successful.
 public static  void main(String[] args) 
    Receives a todo list XML instance, twice rendering it invalid and validating it using the XMLBeans API.
 public XmlObject parseXml(String xmlFilePath,
    XmlOptions validationOptions) 

    Creates a File from the XML path provided in main arguments, then parses the file's contents into a type generated from schema.

    Note that this work might have been done in main. Isolating it here makes the code separately available from outside this class.

 public  void printErrors(ArrayList validationErrors) 
    Receives the collection containing errors found during validation and print the errors to the console.
