我想删除所有说“SetActiveLocale”并具有“en”值的事务，除了第一个 SetActiveLocale 事务。我正在使用 XML 文档来存储整个字符串文件。

这是一个简洁的方法来做你正在寻找的东西：

XmlNodeList nodes = doc.SelectNodes("//bmtactionlog/transaction/action[@type='SetActiveLocale']");
XmlNode actionNode = doc.SelectSingleNode("//bmtactionlog");
for(int i = 1; i < nodes.Count; i++)
{
    actionNode.RemoveChild(nodes[i]);
}

这将获取类型为 SetActiveLocale 的所有事务节点，然后删除除第一个节点之外的所有节点。

在这里，我为你写了一个小函数。

这很丑陋，但它确实可以完美地完成工作。

        public static void RemoveDuplicates(string filePath)
    {
        XmlDocument reader = new XmlDocument();
        reader.Load(filePath);

        bool foundApplicable = false;
        ArrayList removeNodes = new ArrayList();
        foreach(XmlNode node in reader.GetElementsByTagName("transaction"))
        {
            if (node.FirstChild != null && node.FirstChild.Attributes["type"].Value == "SetActiveLocale")
            {
                if (node.SelectSingleNode("action/inputparams/param") != null && node.SelectSingleNode("action/inputparams/param").InnerText == "en")
                {
                    if (foundApplicable)
                    {
                        // I have to use a list because foreach breaks if I remove a node while the loop is working
                        removeNodes.Add(node);
                    }
                    else
                        foundApplicable = true;
                }
            }
        }
        foreach (XmlNode node in removeNodes)
        {
            node.ParentNode.RemoveChild(node);
        }
        reader.Save(filePath);
    }
