有没有一个例子显示了geogebra.xml文件的结构,这样我就可以使用另一个程序编写带有自定义数据的文件?

我在这里发布这篇文章是为了通过提供一种简单通用的方法来解决这个问题,让其他人的生活更轻松。

Geogebra的*.ggb文件是一个zip文件,可以将其重命名为*.zip以简化作为zip文件的处理。

检查该zip文件,内容报告为:

$ unzip -l Freq_30.zip
Archive:  Freq_30.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
    11839  2023-10-06 09:50   geogebra_thumbnail.png
       23  2023-10-06 09:50   geogebra_javascript.js
     9860  2023-10-06 09:50   geogebra_defaults2d.xml
     4497  2023-10-06 09:50   geogebra_defaults3d.xml
    26668  2023-10-06 09:50   geogebra.xml
---------                     -------
    52887                     5 files
$ 

正如我们所看到的,zip文件中有许多XML文件。所有这些文件都可以提取到一个文件夹中进行操作。我强烈建议您在操作内容之前,先复制这些文件作为备份。

在查看了这些文件后,我得出结论,唯一一个包含实际几何结构的文件( 与查看、方向或GUI无关 )是 geogebra.xml 文件

我创建了一个非常简单的*.ggb模型,使用最少的元素来解开这个谜题。对于我的简化模型,我能够将geogebra.xml文件“分解”为( 正如我所感知的 )逻辑组件。这些是:

-rw-rw-r-- 1 user group 5012 Oct  9 21:08 geogebra.xml__01_HEADER
-rw-rw-r-- 1 user group 1587 Oct  9 21:04 geogebra.xml__02_GEOMETRY_POINT
-rw-rw-r-- 1 user group 1722 Oct  9 21:05 geogebra.xml__03_GEOMETRY_SEGMENT
-rw-rw-r-- 1 user group 1929 Oct  9 21:06 geogebra.xml__04_GEOMETRY_FACE
-rw-rw-r-- 1 user group  288 Oct  9 21:06 geogebra.xml__05_TRAILER

我的每一个最终版本的内容都包含在后面(下面),供研究/审查/参考。

在操作这些文件使我满意之后,我从新创建的部分(Linux中的简单cat命令)重新构建了geogebra.xml文件。

在保留了构成原始*.ggb文件的其他文件后,我使用zip命令的适当形式创建了一个新的*.ggb。随后,*.zip文件被重命名为Geogebra所期望的*.ggb格式。

使用Geogebra中的“文件/打开”选项,我能够成功地加载带有修改后的几何体的新文件,并继续操作该文件而不会出现问题。

我创建了一个简单的脚本 ( 地理_构建自定义模型.sh )以简化从组件部件重建*.gbb文件的过程,即:
