20-4. Validating XML
Problem
You want to confirm that your XML is valid—that it conforms to a known document
definition or schema.
Solution
Validate that your XML conforms to a specific schema by using the
javax.xml.validation
package. The following code snippet from
org.java8recipes.chapter20.recipe20_4.ValidateXml
demonstrates
how to validate against an XML schema file:
import java.io.File;
import java.io.IOException;
import javax.xml.XMLConstants;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
