由于需要将百度脑图的内容导出为xml或者json格式，发现百度脑图只能导出为树形文本，所以就写了个小应用给编辑用。
/// <summary>/// 树形文本转xml/// </summary>/// <param name="txt"></param>/// <returns></returns>public static string Txt2Xml(string txt){//创建XDocument对象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;//父节点var parentEle = xmlDoc.Descendants("level").LastOrDefault(p => p.Value == (level - 1).ToString())?.Parent;//新节点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内容**///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转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 ??
