需要PyXB帮助

Question

因此，我使用PyXB创建了python绑定，以便基于xsd模式创建一个xml文件。

模式如下：

​

<?xml version="1.0" encoding="UTF-8"?>

我想做的是使用pyxbgen生成的模块创建一个XML，但我不知道如何创建。pyxb文档中的示例对我没有帮助。

我试着在这里发布这个模块，但是它太大了。

有没有人能给我一个至少从哪里开始的见解？

非常感谢!

我也有同样的问题。要下载源代码，请参考下面的示例。然后从主存储库转到./examples/manual/demo2.sh。我使用的是git版本PyXB-1.2.4。

示例：

cd to some_dir
git clone https://github.com/pabigot/pyxb.git
git checkout PyXB-1.2.4.

然后转到.pyxb/examples/manual目录查看演示。

如果你需要更多的帮助，请在评论中告诉我。
