To get any node, you can use this
要获取任何节点，您可以使用它
Set queryNode = xmlDocument.selectSingleNode(".//node()[@context = 'General']")
or, specifically for the addnode
或者，专门针对add节点
Set queryNode = xmlDocument.selectSingleNode(".//add[@context = 'General']")
This is using XPath, which may require you to set the selection namespace property of the DomDocument
这是使用 XPath，这可能需要您设置 DomDocument 的选择命名空间属性
xmlDocument.setProperty "SelectionLanguage", "XPath"
You might want to search for a XPath tutorial, such as w3schools- New Link
您可能想搜索 XPath 教程，例如w3schools- 新链接
