主观操作题的XML形式化表达及自动评阅

提出一种基于XML技术实现Access操作题自动评阅的策略及实现方法。从数据库中提取对象的操作信息后，首先参照操作点配置文件，对操作信息进行过滤，然后用XML形式化表示，并将XML标记与数据库对象属性自动关联，通过对XML文档的解析实现自动评阅。详细介绍了配置文件的设置、XML的形式化表达、适应操作题灵活性多样性的评阅策略和错误的定位反馈。评阅系统在实际教学中得到有效应用，不仅适合考试题，也适合平时实验作业的评阅。

Formal Expression of Subjective Operation in XML and its Auto-Checking

An automatic checking strategy and realization method for Access operations based on XML technique was given. First, operation information was extracted into a text file. Then, the data of txt format was expressed in simple and easy XML as filtered by the configuration file recording operation points, with the tag was related to database Attributes. Finally, the XML documents from the model and the student were analyzed and compared to implement checking. In the article the method of the extraction, the construction of the configuration, the XML representation, the checking strategies accommodated to flexibility and diversity, and the errors locating was discussed in details. The system has been used in teaching effectively. It is applied to the test as well as homework.
