摘　　要：将XML支持集成到Java语言,XJ允许编译器在早期检测错误并报告。XJ通过XML Schema声明,编译器可按照其约束进行检验,以确保XML数据使用正确。XJ通过编写内联XML构造XML数据。编译器根据声明类型检验XML是否有效,以优化构造。XJ通过将XPath表达式的知识引,编译器将根据元素的XML Scheme类型验证其XPath计算是否适当,并能生成计算XPath表达式的最优化代码。XML was integrated in Java language. The XJ could allow the compiler to detect eady error and report. XJ declared through XML Scheme; the compiler carried out the verifying according to restriction to maker sure the right use of XML data. XJ constructed the XML data through compiling inter-linkage XML. The compiler verified the XML efficiency to optimize the formation. The XJ introduced knowledge of XPath expressions. The compiler verified the XPath calculation was appropriate based on XML Scheme type of element. And the optimize code for XPath expression calculation was generated.
