Of course, you can also try the example specifying the schema location by the second argument on the
command line.
How It Works
The only significant difference from what you had in the previous example that processed a document
with a DTD is the creation of the Schema object to identify the schema to be used. When you supply a
second command-line argument, a File object encapsulating the schema file path is created and a ref-
erence to this is passed as the second argument to the process() method. The process() method uses
the second argument that you pass to it to determine how to create the Schema object that is passed to the
setSchema() method for the SAXParserFactory object:
SchemaFactory sf =
SchemaFactory.newInstance(W3C_XML_SCHEMA_NS_URI);
spf.setSchema(schemaFile == null ? sf.newSchema() :
sf.newSchema(schemaFile));
