Question

这是我正在运行的命令:

xsd.exe -c -l:c# D:\Documents\DEV\SARPilot\Docs\schemas\06-141r2\06-141r2.xsd

这些是我遇到的错误:

XSD 文件是从以下文档的附录 A 中复制/粘贴的: http://services.eoportal.org/portal/documents/06-141r2_Ordering_Services_for_Earth_Observation_Products_0.9.2.pdf

您链接的 PDF 文档中包含的 XML 模式引用了其他几个使用 <import> 的 XSD 文件。元素。您将需要下载这些额外的架构文件并确保 <import> 中的路径引用元素指向您本地计算机上的正确位置。

如果您仍然遇到错误，那是因为 xsd.exe 无法跟进外部引用。要解决此问题，请直接在命令行中指定所有必需的 XSD 文件，如下所示:

xsd.exe /c MySchema.xsd Import01.xsd Import02.xsd Include01.xsd Include02.xsd

其中 Import01.xsd、Import02.xsd、Include01.xsd 和 Include02.xsd 是通过导入引用的 XSD 文件，并包含 MySchema.xsd 中的元素。
