XML操作，有答案立刻给分

[ybblack001]

现在的XML大致如下

<photos>
  <config auto_play="true" auto_play_duration="2.4" grid_row="4" grid_column="6" tween_duration="0.7" tween_delay="0.02" stylesheet="flashmo_224_style.css" bar_status="1" />
  <photo>
    <filename>photos/flashmo_940x400_01.jpg</filename>
    <description><p class="subtitle">Photo title one goes here</p><p><a href="http://www.flashline.cn" target="_parent">Lorem ipsum dolor sit amet</a>, consectetur adipiscing elit. <span class="highlight">Quisque at ante sit amet</span> erat laoreet <u>fermentum</u>. Quisque nec nisl. Nam scelerisque cursus dolor. Donec in. <span class="note">This text is dynamically loaded from the external XML file. This textfield supports HTML and CSS.</span></p></description>
  </photo>
    <photo>
    <filename>photos/flashmo_940x400_02.jpg</filename>
    <description><p class="subtitle">Photo title two goes here</p><p>Fusce quis diam sit amet tortor luctus pellentesque. <a href="http://www.flashline.cn/donate" target="_blank">Donec accumsan urna</a> non elit tristique mattis. <b>Vivamus fermentum</b> orci viverra nisl. Donec euismod enim et risus. <span class="note">Integer vestibulum luctus leo at iaculis. Nulla scelerisque sodales arcu elementum imperdiet.</span></p></description>
  </photo>
    <photo>
    <filename>photos/flashmo_940x400_03.jpg</filename>
    <description><p class="subtitle">Photo title three goes here</p><p>In velit urna, <u>convallis id</u>, pharetra in, iaculis sit amet, mi. Praesent consectetur imperdiet mauris. Suspendisse at pede vel lorem pulvinar laoreet. Etiam et neque. <span class="note">This text is dynamically loaded from the external XML file. This textfield supports HTML and CSS.</span></p></description>
  </photo>
</photos>

我希望遍历每一个photo
在<description>;</description>后面添加
<transition flow="out" direction="left"></transition>

应该怎么做。

用xmldocument

[子夜__]

XmlDocument dom = new XmlDocument(); 
dom.Load("aaa.xml");//装载XML文档 
int num = 0;
foreach(XmlElement photos in dom.DocumentElement.ChildNodes) 
{ 
string descriptionstr = photos.SelectSingleNode("description").InnerText；
photos.SelectSingleNode("description").InnerText=descriptionstr+"<transition flow="out" direction="left"></transition>"；
}
dom.Save();

参考

改一下 转义一下 <transition flow=\"out\" direction=\"left\"></transition>

photos.SelectSingleNode("description").InnerText=descriptionstr+"<transition flow=\"out\" direction=\"left\"></transition>"；

[ybblack001]

string descriptionstr = photos.SelectSingleNode("description").InnerText;

运行到这一步显示未将对象引用设置到对象的实例。

[ybblack001]

仔细看了下，应该加上一个开关就好了，没注意到开头的配置节，我再试试

[ybblack001]

啊。。和我要的不一样啊。。。
我要的是这种
....
<description>xxxxx</description>
<transition flow="out" direction="left"></transition>
</photo>

自己搞定了。。。。

  foreach (XmlElement photos in dom.DocumentElement.ChildNodes)
        {
             if (i==0)
             {
                 i = 1;
                 continue;
             }
             XmlNode xn = dom.CreateNode(XmlNodeType.Element, "transition", "");
             XmlElement el = dom.CreateElement("transition"); //添加person节点
             el.SetAttribute("flow", "out"); //添加person节点的属性"name"
             el.SetAttribute("direction", "left"); //添加person节点的属性"name"
            string descriptionstr = photos.SelectSingleNode("description").InnerText;
            photos.InsertAfter(xn,photos.LastChild);
        }
        dom.Save(Server.MapPath(@"../flash/" + name));
