搜索在C#中操作xml可找到很多相关教程，此处就不细说了。krpano的全景xml文件和传统xml文件的不同仅在于它们的根不一样，vtour.xml文件的根为：
<krpano version="1.19" title="">
</krpano>
每个全景一般都包含有include、skin_settings、action这三个子元素，之后才是场景scene，scene里有自己的属性，还有view、hotspot等子元素。
还需要明确的是，每个场景都一一个唯一名称，原始名称为图片名（没有后缀），在xml文件里，name指示这个唯一名称，在panos瓦片文件夹里，每个场景瓦片的文件夹名则为这个唯一名称，加入全景照片为123.jpg，则：
//场景名称，唯一
//注意如果不要scene，则场景名称不能以数字开头，但如果去掉scene，则很多地方也要跟着修改（同样，热点名称也不能以数字开头）
name="scene_123"
//在浏览场景时显示的名称，可以修改
title="123"
//瓦片文件夹名称，后面会加上.tiles
“123.tiles”
下面来看具体的操作：
在进行操作前要引用命名空间
加载xml文件及保存
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlpath); //xml绝对路径 加载xml文件
RenameScene(xmlDoc, "name1", "title1"); //修改title
MoveScene(xmlDoc, ["name1", "name2"]); //更改场景顺序
DeleteScene(xmlDoc, "name1"); //删除场景
RaiseScene(xmlDoc, ["name1", "name2"], "raisename", "after"); //添加场景
ReplaceScene(xmlDoc, ["name1", "name2"]); //替换场景
SetView(xmlDoc, "name1", "10", "20.5"); //设置进入场景时的初始视角
xmlDoc.Save(xmlpath); //保存xml文件
修改场景显示名称：操作xml文件
/// <summary>
/// 修改场景显示名称title
/// </summary>
/// <param name="xmlDoc">xml文件</param>
/// <param name="sceneid">场景唯一名称name</param>
/// <param name="scenename">scenename</param>
/// <returns>成功/失败</returns>
private string RenameScene(XmlDocument xmlDoc, string sceneid, string scenename)
{
try
{
XmlNode renameNode = xmlDoc.DocumentElement.SelectSingleNode("/krpano/scene[@name='scene_" + sceneid + "']");
XmlElement element = (XmlElement)renameNode;
element.SetAttribute("title", scenename);
return "success";
}
catch (Exception ex)
{
return "failed";
}
}
更换场景顺序：操作xml文件
/// <summary>
/// 更换场景顺序：根据新顺序将要排放的场景结点放到栈或者队列中，然后重新排位置，注意栈和队列的出入顺序
/// </summary>
/// <param name="xmlDoc">xml文件</param>

public string MoveScene(XmlDocument xmlDoc, string[] sceneid)

Stack<XmlNode> tourNode = new Stack<XmlNode>();
for (int len=sceneid.Length, i = len - 1; i > -1; i--)
{
XmlNode moveNode = xmlDoc.DocumentElement.SelectSingleNode("/krpano/scene[@name='scene_" + sceneid[i] + "']");
tourNode.Push(moveNode);
rootNode.RemoveChild(moveNode);
}
while (tourNode.Count() > 0)
{
rootNode.AppendChild(tourNode.Pop());
}
return "success";
}
catch (Exception ex)
{

}
}
删除场景：操作xml文件、panos/*.tiles文件夹
/// <summary>
/// 删除场景

{
try
{
XmlNode selectNode = xmlDoc.SelectSingleNode("/krpano/scene[@name='scene_" + sceneid + "']");
selectNode.ParentNode.RemoveChild(selectNode);
//删除场景对应的瓦片图片文件夹，注意路径
//后面有“true”，表示删除这个文件夹及其子目录
Directory.Delete("../panos/" + sceneid + ".tiles", true);
return "success";
}
catch (Exception ex)
{
return "failed";

添加场景：操作xml文件、panos/*.tiles文件夹
