Question

我有这段代码：

XmlDocument doc = new XmlDocument();
doc.Load(file_data);
XmlNamespaceManager namespace_xml = new XmlNamespaceManager(doc.NameTable);

//adicionar todos os namespaces necessarios
foreach (KeyValuePair<string, string> namespace_elem in all_namespaces)
{
    namespace_xml.AddNamespace(namespace_elem.Key, namespace_elem.Value);
}

XmlNodeList node_list = doc.DocumentElement.SelectNodes("//w:tr//w:tc//w:p", namespace_xml);
Regex rgx = new Regex(@"^\{\{[a-zA-Z0-9_]+\}\}$");

for (int i = 0; i < node_list.Count; i++)
{
    XmlNode node_elem = node_list[i];
    Match mtch = rgx.Match(node_elem.InnerText);

    if (mtch.Success)
    {
        //caso seja uma linha que tenha de ser inserida
        XmlNode ancestor_node = null;
        XmlNode aux_node_elem = node_elem;

        while(aux_node_elem.ParentNode != null)
        {
            if (aux_node_elem.ParentNode.Name.Equals("w:tr"))
            {
                ancestor_node = aux_node_elem.ParentNode;
                break;
            }

            aux_node_elem = aux_node_elem.ParentNode;
        }

        ancestor_node.Clone();
        doc.Save(file_data);
        break;
    }
}

我想在XML文件中找到一个节点，其文本以＆＃34; {{＆＃34;并以＆＃34;}}＆＃34;结束并复制他的父亲。我可以找到那个节点，但我不能复制他的父亲。以下代码是我想要使用的XML：

我尝试了一切但我无法在XML文件中添加新节点。我做错了什么？

Answer 1

您忽略了ancestor_node.Clone();的返回值。它返回XmlNode。再次在文档中插入一个。
