Question

我正在从网站上搜索公司名称。网站以XML格式返回响应。我试图将XML转换为自定义列表。我已将XML响应转换为XDocument，但未检索到我尝试获取的节点值。我之前没有这样做，所以我不知道该怎么做。下面是XML响应，

.Set<T>

因为我是新手，所以我尝试不同的东西。以下所有行都不返回任何数据，

请指导我如何检索每个CoSearchItem节点的公司名称和公司编号。感谢

指定命名空间：

XNamespace ns = "http://xmlgw.companieshouse.gov.uk/v1-0/schema";
var results = xDocument.Descendants(ns + "CoSearchItem")                                
                                  .Select(n => new 
                                  { 
                                       CompanyName = n.Element(ns +"CompanyName").Value, 
                                       CompanyNumber = n.Element(ns +"CompanyNumber").Value 
                                   })
                                   .ToList();

没有从XDocument获得所需的元素
