Class XMLGrammarPreparser

    java.lang.Object
      org.apache.xerces.parsers.XMLGrammarPreparser

    public class XMLGrammarPreparser

extends java.lang.Object

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.
