访问XML Schema的Java API的实现

Implementing a Java API for Access to XML Schema

W3C XML Schema定义语言是一个描述和约束XML(可扩展标记语言)文档内容的XML语言,它定义了一组承载XML文档结构定义的核心语义的抽象组件.目前为止还没有访问这些组件和结构的标准API(应用程序接口).MARKUPTechnology公司仅仅定义了一个JavaAPI去访问XMLSchema,但并没有真正实现.本文在此定义下,基于一个开源JavaXML解析器Xerces2,实现了一个SchemaAPI去访问这个XML语言.

W3C XML Schema defines a set of abstract components, which carry the core semantics of document structure definition. There is as yet no standard API for accessing these components and their structure. The MARKUP Technology Company has specified a Java API for accessing XML Schema but it has not been implemented yet. This paper gives an implementation for this API on the basis of an open source Java XML parser, Xerces2.
