由于需要將百度腦圖的內容導出為xml或者json格式，發現百度腦圖只能導出為樹形文本，所以就寫了個小應用給編輯用。

/// <summary>/// 樹形文本轉xml/// </summary>/// <param name="txt"></param>/// <returns></returns>public static string Txt2Xml(string txt){//創建XDocument對象var xmlDoc = new XDocument();//逐行提取文本var txts = txt.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);foreach (var tt in txts){var title = tt.TrimStart('\t').Trim();if (title == "") continue;var level = tt.Length - title.Length;//父節點var parentEle = xmlDoc.Descendants("level").LastOrDefault(p => p.Value == (level - 1).ToString())?.Parent;//新節點XElement newChildEle;if (parentEle == null)xmlDoc.Add(newChildEle = new XElement("data"));elseparentEle.Add(newChildEle = new XElement("children"));newChildEle.Add(new XElement("topic", title));newChildEle.Add(new XElement("level", level));/**可以添加其它需要的內容**///newChildEle.Add(new XElement("direction", "right"));//newChildEle.Add(new XElement("expanded", true));}xmlDoc.Declaration = new XDeclaration("1.0", "UTF-8", null);return xmlDoc.Declaration + "\r\n" + xmlDoc;}/// <summary>/// xml轉json/// </summary>/// <param name="xmlTxt"></param>/// <returns></returns>public static string Xml2Json(string xmlTxt){return JsonConvert.SerializeXNode(XElement.Parse(xmlTxt), Newtonsoft.Json.Formatting.Indented);}public void SaveToFile(string txt, string type){if (type == "xml"){var xmlDoc = new XmlDocument();xmlDoc.LoadXml(txt);_txtTitle = xmlDoc.DocumentElement?.SelectSingleNode("topic")?.InnerText;}else{var jo = JObject.Parse(txt);_txtTitle = jo["data"]?["topic"]?.ToString();}var sfd = new SaveFileDialog{Filter = @"" + type + @" file|*." + type + "",FilterIndex = 2,RestoreDirectory = true,FileName = _txtTitle ?? "untitled"};var dr = sfd.ShowDialog();if (dr == DialogResult.OK && sfd.FileName.Length > 0){using (var fsw = new StreamWriter(sfd.FileName, false)){fsw.Write(txt);fsw.Close();fsw.Dispose();}new MessageBoxTimeOut().Show(1000, @"保存成功。", @"提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}}
