Examples of XMLGrammarPreparser

com.sun.org.apache.xerces.internal.parsers.XMLGrammarPreparser

This class provides an easy way for a user to preparse grammars of various types. By default, it knows how to preparse external DTD's and schemas; it provides an easy way for user applications to register classes that know how to parse additional grammar types. By default, it does no grammar caching; but it provides ways for user applications to do so. @author Neil Graham, IBM @version $Id: XMLGrammarPreparser.java,v 1.7 2010-11-01 04:40:10 joehw Exp $
