Package containing regular expressions and DTD. There are three central classes contained in this package:
DTD
which encapsulates Document Type DefinitonNDFA
which representa a nondeterministic finite automaton
used to recognize words confroming to a regular expression
Tag
which facilitates efficient creation and identification
of tags in the system (this class is also a regular expression
ValidationAutomaton
which checks if a
token stream
conforms to
a given DTD
.
