LINQ-to-XML中的InnerText相当于什么？

Question

我的XML是:

<CurrentWeather>
  <Location>Berlin</Location>
</CurrentWeather>

我想要字符串"Berlin",如何从元素Location中获取内容,比如InnerText？

XDocument xdoc = XDocument.Parse(xml);
string location = xdoc.Descendants("Location").ToString(); 

以上回报

System.Xml.Linq.XContainer + d__a

Answer 1

对于您的特定样品:

string result = xdoc.Descendants("Location").Single().Value;

但是,请注意,如果您有更大的XML示例,则Descendants可以返回多个结果:

<root>
 <CurrentWeather>
  <Location>Berlin</Location>
 </CurrentWeather>
 <CurrentWeather>
  <Location>Florida</Location>
 </CurrentWeather>
</root>

以上代码将更改为:

foreach (XElement element in xdoc.Descendants("Location"))
{
    Console.WriteLine(element.Value);
}

Answer 2

public static string InnerText(this XElement el)
{
    StringBuilder str = new StringBuilder();
    foreach (XNode element in el.DescendantNodes().Where(x=>x.NodeType==XmlNodeType.Text))
    {
        str.Append(element.ToString());
    }
    return str.ToString();
}
