You can perform XML Schema validation with the sax\Writer.java program provided in the Apache Xerces package as shown below.

Run the sax\Writer.java program with "-v -s" option to turn on XML Schema validation. If the input XML file does not meet the requirements of its Schema, you will see validation errors:
