Question

我的XML是：

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

我想要字符串“Berlin”，如何从元素位置中获取内容，如 InnerText ？

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

以上返回

System.Xml.Linq.XContainer + d__a

Answer 1

对于您的特定样本：

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

但是，请注意，如果您拥有更大的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>

上述代码将更改为：

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();
}

Answer 3

string location = doc.Descendants("Location").Single().Value;

Answer 4

string location = (string)xdoc.Root.Element("Location");

Answer 5

在单个元素的简单情况下，

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

string location = xDocument..Descendants("CurrentWeather").Element("Location").Value;

像这样的多个元素，

<CurrentWeather>
    <Location>Berlin</Location>
    <Location>Auckland</Location>
   <Location>Wellington</Location>
</CurrentWeather>

  foreach (var result in xDocument.Descendants("CurrentWeather").Select(x => new{ location = x.Element("Location").Value.Tostring() }))
        {
          Locations + = location ;
        }

LINQ-to-XML中的InnerText相当于什么？
