我很难解析同时具有属性和后代的节点。

我需要进入客户节点并将其下方的所有内容解析为在网页上使用的值。

var contacts = from c in xdoc.Descendants("contact")
               select new Contact
               {              
                   Email = (string)c.Element("email"),
                   HomePhone = (string)c.Element("phone").Attribute("type") // ?
               };

还有我的 XML：

    <customer>
          <contact>
            <name part="first">Rick</name>
            <name part="last">Smith</name>
            <email>rick@yahoo.com</email>
            <phone type="home">2299998989</phone>
            <phone type="work">2298887878</phone>
            <phone type="cell">2297778878</phone>
            <address type="home">
              <street line="1">4001 Coleman Rd</street>
              <street line="2">Ste. 99</street>
              <city>Tempe</city>
              <regioncode>AZ</regioncode>
              <postalcode>43444</postalcode>
            </address>
          </contact>
          <comments>Customer comments</comments>
        </customer>

        <vendor>
          <contact>
            <name part="full" type="salesperson">Joe Smith</name>
          </contact>
        </vendor>

XDocument xdoc = XDocument.Load(path_to_xml);
var customers = 
    from c in xdoc.Descendants("customer")
    let contact = c.Element("contact")        
    let names = contact.Elements("name")
    let phones = contact.Elements("phone")
    let address = contact.Element("address")
    let streets = address.Elements("street")
    select new Customer {
        Contact = new Contact {
            FirstName = (string)names.SingleOrDefault(n => (string)n.Attribute("part") == "first"),
            LastName = (string)names.SingleOrDefault(n => (string)n.Attribute("part") == "last"),
            Email = (string)contact.Element("email"),
            HomePhone = (string)phones.SingleOrDefault(p => (string)p.Attribute("type") == "home"),
            CellPhone = (string)phones.SingleOrDefault(p => (string)p.Attribute("type") == "cell"),
            WorkPhone = (string)phones.SingleOrDefault(p => (string)p.Attribute("type") == "work"),
            Address = new Address {
                    Type = (string)address.Attribute("type"),
                    StreetLine1 = (string)streets.SingleOrDefault(s => (int)s.Attribute("line") == 1),
                    StreetLine2 = (string)streets.SingleOrDefault(s => (int)s.Attribute("line") == 2),
                    City = (string)address.Element("city"),
                    RegionCode = (string)address.Element("regioncode"),
                    PostalCode = (string)address.Element("postalcode")
                }
        },
        Comments = (string)c.Element("comments")
    };

您需要以下类来保存解析的数据：

public class Customer
{
    public Contact Contact { get; set; }
    public string Comments { get; set; }
}

public class Contact
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string HomePhone { get; set; }
    public string WorkPhone { get; set; }
    public string CellPhone { get; set; }
    public Address Address { get; set; }
}

public class Address
{
    public string Type { get; set; }
    public string StreetLine1 { get; set; }
    public string StreetLine2 { get; set; }
    public string City { get; set; }
    public string RegionCode { get; set; }
    public string PostalCode { get; set; }
}

要获取家庭电话号码，您应该使用：

HomePhone = (string)c.Elements("phone").SingleOrDefault(e => (string)e.Attribute("type") == "home");
