我正在尝试从我正在编写的程序中以编程方式访问 XML 格式的 NOAA 每日潮汐预测数据（即每天的高潮和低潮时间）。数据可从 NOAA 网站免费获得。问题是似乎没有用于获取 XML 数据的 URL。相反，在我看来，它就像需要单击一个表单按钮，该按钮又运行一些下载 XML 文件的 JavaScript。无论如何，是否可以从 WGET 或 CURL 命令访问每日 xml 数据？

例如潮汐数据的 URL 是：NOAA URL

我尝试以编程方式下载的文件可通过Download: XML右侧的按钮访问。

The form named "dataform" is made to open in a new window due to the target="_blank" attribute.

If you go to that page in Chrome, and open Developer Tools, you can remove the target="_blank" attribute. Then click the "XML" button again and you will see the call in the network tab.

Here is the call in cURL:
