未从 XDocument 获取所需的元素

Not getting desired elements from XDocument

我正在从网站搜索公司名称。网站 return 的响应为 XML。我正在尝试将 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。我以前没有这样做过,所以我不确定该怎么做。下面是 XML 响应,

     </CoSearchItem>
     <CoSearchItem>
        <CompanyName>Company 2</CompanyName>

        <CompanyNumber>0655421</CompanyNumber>
     </CoSearchItem>
  </NameSearch>
</Body>
</GovTalkMessage>

因为我是新手所以我正在尝试不同的东西。以下所有行return无数据,

var v1 = xDocument.Descendants("GovTalkMessage").Elements("CoSearchItem");
var v2 = xDocument.Descendants("Body").Elements("CoSearchItem");
var v3 = xDocument.Descendants("NameSearch").Elements("CoSearchItem");

请指导我如何为每个 CoSearchItem 节点检索公司名称和公司编号。谢谢

命名空间的帐户:

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();
