1.The dissertation studies the technical features of XML schema language—DTD and XML Schema, especially the powerful functions of XML Schema and the relationship of XML Schema and XML, and it also expounds the importance of XML Schema in the XML querying, especially the structure querying.
论文研究了XML模式语言??DTD和XML Schema的技术特点,特别是XML Schema的强大功能以及它与XML的关系,阐述了XML Schema在XML查询特别是结构查询中的重要作用; 举例说明了XML查询语言??XPath和XQuery的语法特点;
2.Query XML data used DTD or Schema is the usual the method, which need DTD or Schema can describe the structure of the XML data.
利用DTD或者schema对XML数据进行查询是目前较多使用的方法，这需要DTD或者schema能够准确的表示出XML数据的结构。
3.The new standard and new technology of the combination of XML and STEP also have been introduced in details in this article. The schema which is represented by EXPRESS language is mapped into XML DTD/Schema so as to bring about the XML implementation methods of STEP standard.
并详细地介绍了将XML与STEP相结合的新技术、新标准，将由EXPRESS语言所描述的schema映射为XML的DTD/Schema，实现STEP标准的XML实现方式。
4.XML is now on the way to be a new standard for data representation and exchange. First, this thesis analyses the schema of XML data and document, researches several main XML Schemas : DTD、 W3C Schema and Relax NG through comparing method because xml schema languages exist in kind of types with different features and advantages.
本文首先针对XML语言分析了它的数据和文档组织的模式，因为XML的模式语言有很多种，并且各自有各自的特点和优势，所以本文通过比较的方法研究了DTD、W3C Schema和Relax NG等几个主要的XML模式语言。
5.Thirdly,the transform is realized from UML model to XML schema according to the corre-sponding map mechanism.
最后,根据定义的UML模型到XML Schema的映射机制,实现UML方法描述的信息数据对象模型到XML Schema的转换,从而建立了基于XML Schema的电子病历数据模式。
6.The key point is its extensibility by which the user can define his data property and lables freely, employ DTD (Document Type Definition) or XML Schema to describle the logical structure of XML schema and define the elements, property of elements and the relation between them.
XML语言具有自描述性、良好的数据存储格式、可扩展性、高度结构化、内容与形式分离等特点,其最大的特点是它的可扩展性,用户可以随意定义适合自己的数据属性和标签,采用DTD(Document Type Definition)或XML Schema来描述XML文档的逻辑结构,定义XML文档中的元素、元素的属性以及各元素、元素和属性之间的联系。
7.According to the complex situation of IDS alert information at home and abroad, the general requirement of standardized alert information is studied thoroughly and the content of intrusion detection alert is analyzed in detail, based on which the idea of using Schema on modeling alert information is proposed, subsequently, the Alert Information Schema Model(AISM) is constructed and optimized.
针对国内外IDS产品入侵检测信息纷杂的现状,探讨了标准化报警信息格式的要求,详细分析了入侵报警所要表达的具体内容; 在此基础上提出并采用Schema(模式)对报警信息建模的思想,完成了AISM(报警信息模式模型)的构建,同时对该模型进行了优化,最终形成统一报警信息格式提案;
8.2. Finite automata representations of XML, XML Schema and path expression and the correlation relationship between XML NFA and Schema DFA.
2)以有限自动机为工具,给出了XML,XML Schema,路径表达式的自动机表示形式,以及它们之间的关系。
9.XML Schema is presented and compared with XML DTD.
介绍了XML Schema的特点,比较了XML DTD和XML Schema。
10.Then the article gives a brief account of the related contents of PDM ,such as origination, development, function and perspective, and the related standard of XML, for example, DTD (Document Type Definition ), Schema, XSL (extensible Stylesheet Language) andXLL (XML Link Language) .
接下来概括地介绍了PDM技术的起源、发展、功能及前景等和XML的相关标准，如DTD、Schema、XSL、XLL等。
