c# - XPathSelectElement 总是返回 null

Question

string xml = @"<vehicle>   <cars>     <car>tet</car>    </cars> </vehicle>";
XElement x = XElement.Parse(xml);
var node = x.XPathSelectElement("//vehicle/cars");

为什么节点总是空的？

Answer 1

XPath 应该是

var node = x.XPathSelectElement("cars");

输出：

<cars>
  <car>tet</car>
</cars>
