基于XML的Web信息筛选器的设计与实现

为了给用户提供有效信息,能够根据用户的需要对Internet上的网页信息进行获取和过滤,设计了一个基于XML的Web信息筛选器。系统利用了XML作为中间数据的数据交换技术将Microsoft.NET技术、数据库技术与XML技术相结合设计并实现Web服务程序。采用在Web服务和客户端应用程序之间使用基于XML的存储和访问技术进行数据交换与处理的实现方法,构建了一个基于XML的Web服务,进行解析并过滤多余的信息,将解析后有用的信息结果返回给请求数据的客户端,实现为用户提供特定信息的服务。

Design and implementation of Web information filters based on XML

In order to provide effective information for the user,acquiring and filtering the information from the page on the Internet according to the needs of the users,the design of Web information filters based on XML is designed in this paper.The design and implementation of the Web service program is combined with Microsoft.net,database and XML technology based on XML as a kind of middle data of data exchange technology.By using the implement method on how to deal with the data based on XML data storage and access technology between Web Services and client applications,the XML Web Service to provide the specific information for the users is build,which can return the useful information to the client for requesting data after analyzing and filtering the redundant information.
