我有一个Windows窗体，该Web窗体提供了WebBrowser控件，我需要下载XML文件，但是“下载”按钮使用JavaScript即时生成了URI，因此我无法通过以下方式引用保存XML的URL / URI一行代码。因此，我所做的就是通过其ID抓取该元素，然后调用“ click”按钮。那不好，因为我需要知道我下载的XML文件的名称并知道它的去向，因此我可以引用该文件并进行解析。
这是按钮的HTML：
<button type="button" id="__button35" data-sap-ui="__button35"
role="button" aria-disabled="false" tabindex="0"
class="HB-14-1E3F57 extTextLinkDark sapUiBtn sapUiBtnIconAndText
sapUiBtnNorm sapUiBtnS whiteToolPopupListLink sapUiBtnStd"><img
id="__button35-img" src="costco/resource/image/xmlIcon.png"
alt="" role="presentation" class="sapUiBtnIco sapUiBtnIcoL"><span
class="sapUiBtnTxt">Download Details as XML</span></button>
这是单击按钮的简单方法：
var buttonElement = webBrowser1.Document.GetElementById("__button35");
buttonElement.InvokeMember("click");
有人可以帮我找到一种方法，将其发送到我选择的文件夹中，为xml文件指定一个不同的名称，或者甚至在下载时捕获它，以便我可以解析数据吗？谢谢。

我通过取消Windows窗体并完全依赖于使用宏记录器，C＃控制台应用程序和任务计划程序的自动化来解决了这一问题。首先，我创建了Macro Recorder，以登录网站并导航到相应的页面，选择要下载的最新日期，然后将XML File下载到正确的File文件夹中。然后，我创建了一个C＃应用程序，该应用程序从文件位置中拉出了文件（我不得不将其作为字符串拉入，因为XML文件太大，任何其他方法都会截断数据并使文件成为无效的XML）并解析XML文件，将其加载到SQL Server数据库中，然后将文件存档。所有这些都是通过我的服务器任务计划程序完成的。这是来自C＃主类的代码，这是我发现的解析大型XML文件并确保将每个值都放入数据库中的最佳方法（item标记启动子节点）：
