SAXDemo is to be run from the command line. After verifying that one or two
command-line arguments (the name of an XML document optionally followed by
lowercase letter v, which tells SAXDemo to create a validating parser) have been spe-
cified, main() createsan XMLReader instance;conditionallyenablesthe valida-

DTDhandler,entity resolver,anderrorhandler; installs this Handler instance asthe
value of the lexical-handler property; creates an input source to read the docu-
ment from a file; and parses the document.
The Handler class's source code is presented in Listing 10-11 .
