解决方案

对了，还有，它被称为XPath的。试试这个：

  XmlDocument的DOC =新的XmlDocument（）; 
 doc.Load（@/路径/到/文件）; 
 XmlNode的节点= doc.SelectSingleNode（/影片/视频/ thumbnail_large）; 
字符串URI = node.InnerText; 
  

至少这是我可以从这个糟糕的格式文件读取。如果您使用的是两个不同的字母（视频细节和HTML标记），你应该考虑使用的命名空间。

I am trying to pull the <thumbnail_large>http://b.vimeocdn.com/ts/235/662/23566238_640.jpg</thumbnail_large> value from the thumbnail_large element in a created xml file. Is there a way to pull that value without looping through the who xml file? Thanks for any help.

解决方案

Yes, there is and it is called XPath. Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"/path/to/file");
XmlNode node = doc.SelectSingleNode("/videos/video/thumbnail_large");
string URI = node.InnerText;

At least that is what I can read from this poorly formatted file. If you are using two different alphabets (video details and HTML markup) you should consider using namespaces.
