Question

您好我有一串XML，我希望使用C＃在特定位置插入另一个XML块。

＆LT;测试＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT; /试验＆gt; ＆LT; Lol＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT; /洛尔＆GT;

我想在最后一个＆lt;之后插入一个字符串/组＆gt;里面＆lt;测试＆gt;使其看起来像

＆LT;测试＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT;我添加了这个组＆gt; ＆LT; /我添加了这个组＆gt; ＆LT; /试验＆gt; ＆LT; Lol＆gt; ＆LT;组＆gt; ＆LT; /组＆gt; ＆LT; /洛尔＆GT;

如果有人知道怎么做，请告诉我。

提前致谢。

字符串不仅仅是单个元素，而且可能包含数百个元素和子元素以及子子元素和许多不同的属性。 elementception 这是一个类似于如何看待的样本：

您可以执行以下操作，首先将字符串加载为xml

   string xmlContent = "Your xml string content";
   //parse the string as xml
   XDocument xmlDoc = XDocument.Parse(xmlContent);
   //get the element which matches your need.
   XElement areaElement = 
       (from el in xmlDoc.Descendants("area") where el.Attribute("id").Value=="workplace"
       select el).FirstOrDefault();
   //create a new group element
   XElement newGroup = new XElement("i added this group");
   //add a value for this element or add attributes what ever is needed to this group here
   //add the new group this will by default add it at the end of all other child elements.
   areaElement.Add(newGroup);
