超文本标记语言HTML简介   总被引:1,自引:0,他引:1  
一、HTML概述HTML是在标准通用标记语言(SGML)基础上建立起来的用于描述超文本的标记语言.SGML是ISO在1986年公布的文本描述标准(ISO8879);超文本是含有指向其它文档的指针的文本;标记是描述或分割文本中各对象的一种编码.二、HTML文件的结构与组成HTML文件为标准的ASCⅡ文本文件,是由各种具有语义的对象所构成的逻辑结构体.例如一份HTML文件可由标题、段落、列表、表格、单字及其它对象组成.在实际应用中,  相似文献

网上表格数据到XML的自动转换   总被引:3,自引:0,他引:3       下载免费PDF全文
互联网上有大量信息采用HTML表格表示,由于HTML不描述数据的内容,机器不能理解和查询。论文利用HTML表格属性,在表格中插入冗余单元,使HTML表格规范化;对没有标志表头的HTML表格,采用格式化的信息的量化值识别网上表格的表头。在此基础上,提出了通过获取表格属性与值对应的语义层次,自动转换HTML表格数据为XML文挡的新方法。  相似文献

XML与HTML整合     
XML与HTML都是重要的网络标识语言,但各自具有优缺点,XML侧重于数据的描述,HTML侧重于数据的显示,若将两者整合则可以取长补短。主要介绍如何使用数据岛技术来实现XML与HTML的整合。  相似文献

随着Internet的发展,以HTML格式显示的Web数据越来越不适应新的发展需求,而用来描述和存储数据的XML语言有着许多优于HTML的技术,于是将HTML格式的数据用XML格式表示出来,是现在网络应用中需要解决的问题。这里介绍的基于Web的HTML到XML数据转换方法能够有效地把HTML格式的文件转换成XML(XHTML)格式的文件。  相似文献

说到WWW,就不能不提到HTML。HTML是“HyperText Markup Language”的缩写,这是WWW服务器上书写WWW文件所使用的语言,是结构化通用标记语言(SGML)的一个子集。使用HTML,能够描述Web文档的结构,包括诸如多媒体集成和超文本链接使用的有关信息。它还将Java applet与用户的Web节点进行链接。起初,HTML没有标准定义。换言之,没有具体  相似文献

三、超文本标记语言(HTML) 标准通用化标记语言(SGML,即Standard General-ized Markup Language)是一种元语言,即用来描述标记语言的语言。它是一种国际标准,发布于1986年。而超文本标记语言(HTML,即Hyper Text Markup Lan-guage)是SGML的一种应用,它继承了SGML的许多特征。HTML语法是用SGML文档类型定义而成。 HTML拥有一套规范Web文档格式的规则。利用HTML,就可以创建Web文档。用HTML创建的Web文档可以被运行在不同硬件和不同操作系统上的应用程序(如浏览器)所识别,电就是说,HTML文档是与系统平台和应用程序无关的。  相似文献

Originally, HTML was intended to be a simple, rather limited language for describing primitive information layouts in World Wide Web pages. The first version of the HTML specification emphasized simplicity. The browser, not the HTML coder, controlled the actual page appearance, determining the appearance of headers, paragraphs, and other primitive layout elements. In recent years, however, complex features have been added to HTML, including frames, dynamic HTML, and cascading styles. These extensions have served designers well, giving them more control over the appearance of their pages. And today designers have pixel level control over the layout of every element. Unfortunately, these enhancements have ignored the Web user. None of the recent additions to HTML help the user to traverse the Web or to find suitable information quickly. The article describes methods which make the Internet easier to use, including: adding value to links; line thickness control; color usage; icons and pop-ups; and preselection  相似文献

“可扩展标记语言”(XML)是一种简单的与平台无关并被广泛采用的结构化化语言标准。XML相对于HTML的优点是它将用户界面与结构化数据分隔开来,XML不是要替换HTML,实际上XML可以视作对HTML的补充。以下从两个方面浅谈XML与HTML的结合。  相似文献

This paper describes an efficient Web page change detection system based on three optimizations that were implemented on top of the Hungarian algorithm, which we employ to compare trees that correspond to HTML Web pages. The optimizations attempt to stop the comparator algorithm that employs this O(n3) algorithm before it completes all its iterations based on criteria having to do with properties of HTML and heuristics. Analysis and experimental results prove the effectiveness of these optimizations and their ability to render O(n2) performance, where n denotes the number of nodes in the tree. A complete system was implemented and used to carry out the performance experiments. This system includes functionalities and interfaces for processing user requests, fetching Web pages from the Internet, allowing users to select zones in Web pages to monitor, and highlighting changes on the Web pages being monitored  相似文献

Most World-Wide Web information servers provide simple browsing access to collections of static text or hypertext files. This paper describes some interactive World-Wide Web servers that produce information displays and documents dynamically rather than just providing access to static files. The PARC Map Viewer uses a geographic database to create and display maps of any part of the world on demand. The Digital Tradition folk music server provides access to a large database of song lyrics and melodies. These applications take advantage of the multimedia capabilities of World-Wide Web to deliver graphical and audio content as well as formatted text. Hypertext links are used not only for navigation, but also for setting search and presentation parameters. In these applications the HTML format and the HTTP protocol are used like a user interface tool kit to provide not only document retrieval but a complete custom user interface specialized for the application.  相似文献

Traditional server-based web applications allow access to server-hosted resources, but often exhibit poor responsiveness due to server load and network delays. Client-side web applications, on the other hand, provide excellent interactivity at the expense of limited access to server resources. The WebWriter II Editor, a direct manipulation HTML editor that runs in a web browser, uses both server-side and client-side processing in order to achieve the advantages of both. In particular, this editor downloads the document data structure to the browser and performs all operations locally. The user interface is based on HTML frames and includes individual frames for previewing the document and displaying general and specific control panels. All editing is done by JavaScript code residing in roughly twenty HTML pages that are downloaded into these frames as needed. Such a client — server architecture, based on frames, client-side data structures, and multiple JavaScriptenhanced HTML pages' appears promising for a wide variety of applications. This paper describes this architecture, the Meteor Shower Application Architecture, and its use in the WebWriter II Editor.  相似文献
