遍历 XML 节点，添加和删除一些

Question

I have an XML document, where I need to add and remove some nodes while iterating through. But if I'll add nodes like that, the other nodes will be shifted depending on InsertAfter or RemoveChild . So xNode.ChildNodes[i] will point to the wrong node. Of course, I can add or substract counter, but I think it's not a best way. How should I do this?

void Init()
{
    XmlDocument doc = LoadDocument("test.xml");
    RecursiveProcess(doc);
}

void RecursiveProcess(XmlNode xNode)
{
    for(int i = 0; i < node.ChildNodes.Count; i++)
    {
        XmlElement node = xNode.ChildNodes[i] as XmlElement;

        if(/*some condition*/)
        {
            var x = Document.CreateElement("newNode");
            node.ParentNode.InsertAfter(x, node);
        }
        else if(...)
        {
            var x = Document.CreateElement("anotherNode");
            node.ParentNode.RemoveChild(node);
        }

        RecursiveProcess(node);
    }
}

I've found a solution. I have created two queues

NodesToRemove = new Queue<OpenXmlElement>();
NodesToInsert = new Queue<Tuple<OpenXmlElement, OpenXmlElement, InsertMode>>();

And after main document processing I iterate throug the queues and do add/remove operations
