FieldServer观察到的数据每天输出一个XML文件。FieldServer获取的图像文件列表由一个HTML文件输出，其中每天写入一组用于将图像显示为动画的Java脚本的图像文件名。因此，很难将数据和图像作为长期顺序数据进行处理。为了解决这一问题，我们开发了预处理器程序，并利用预处理器的结果为现场服务器开发了数据和图像查看器。预处理器程序使用SAX来分析大量的XML文件。与使用DOM相比，SAX具有更少的内存消耗和更高的处理速度。我们开发了两个浏览器程序，Java Applet版本和Java Servlet版本。前者很容易开发，但启动需要几秒钟。后者在可操作性方面有限制，但它可以在没有Java插件的情况下在Web浏览器上执行
The data observed by a FieldServer is output by one XML file per day. The list of image files taken by a FieldServer is output by one HTML file in which an array of image file names of JavaScript for showing images as animation is written per day. Therefore, it was difficult to process data and images as long-term sequential data. We developed the preprocessor program for solving this problem, and developed the data and image viewer for a FieldServer using preprocessor's result. The preprocessor program uses SAX to analyze a lot of XML files. SAX has merits of less memory consumption and higher speed processing compared with using DOM. We developed two viewer programs, Java Applet version and Java Servlet version. The former is easy to develop, but it takes several seconds to start up. The latter has a restriction in operability, but it can be executed without Java plug-in on a Web browser
