创建全新的XML节点作为子节点附加到其他节点 [英] Create brand new XML node to append as child to other node

问题描述

我想创建一个新的XML节点，以附加到XML文件中的现有节点上. 具体来说，文件的结构为:

I would like to create a new XML node to append to an existing one in my XML file. Specifically, the structure of the file is:

<contract>
    <trade></trade>
    <trade></trade>
</contract> 

我的想法是获取每个<trade>节点，并向其添加一个 new 子级. 这个孩子应该看起来像这样:

My idea is to get each <trade> node and append a new child to it. This child should look like this:

<tradeSource></tradeSource>

我的问题是，如何定义要追加的新子代?似乎我找不到在VBA上创建正确的对象(尽管该项目中已引用了MSXML v3.0库)，而且我无法在网络上的任何地方找到这样的全新节点示例.我的伪代码:

My question is, how do I define this new child to append? It doesn't seem I can find the right object to create on VBA (although the library MSXML v3.0 has been referenced in the project) and I don't manage to find such a sample of brand-new node anywhere on the web. My pseudo-code:

XMLFile.Load(myFileFullName)
Set tradeNodes = XMLFile.getElementsByTagName("trade")
For Each trade In tradeNodes 
    Set newNode = ???? '<-- how to fill this?
    trade.appendChild(newNode)
Next trade

推荐答案

这应该有效:

Set newNode= XMLFile.CreateElement("price");
newNode.InnerText = "19.95"
trade.appendChild(newNode)

请注意，变量trade和newNode都应声明为IXMLDOMNode(在库msxml6.dll中定义的类型).

Please note that both variables trade and newNode should be declared as IXMLDOMNode (type defined in the library msxml6.dll).
