摘要 提出了在应用 XML数据中的一类普遍性问题 ,指出通过定义、处理含 XPath的规则式可有效地提高软件的可扩展性 .阐述如何运用 Java CC实现对 XPath规则式的解析处理 。 A kind of universal problems in application of XML are put forword. And it is pointed out that the expansibilities of software can be improved by defining and handling the rules with XPath . It is expatiated how to use JavaCC to parse expressions with XPath and how to spread this method to other applications.
