如果有三个相同的元素,如何选择XML元素?

/test/contactinfo/contact[type = 'Twitter']/address

如果不起作用,试试看

/test/contactinfo/contact[type/text() = 'Twitter']/address

var profile = doc.Root.Element("profile");

var contactinfo = profile.Element("contactinformation");

var contacts = from contact in contactinfo.Elements("contact")
               where (string)contact.Element("title") == "Twitter"
               select contact;

var result = (string)contacts.Single().Element("value");
