这是我的代码:
XmlTextReader reader = new XmlTextReader(xmlPath);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(reader);
XmlNode root = xmlDoc.DocumentElement;
XmlNode node = root.SelectSingleNode("marketingid");
有效的XML:
<confirmsubmit>
<marketingid>-1</marketingid>
</confirmsubmit>
不起作用的XML:
<confirmsubmit xmlns="http:....">
<marketingid>-1</marketingid>
</confirmsubmit>
处理xmlns属性的方法是什么,我该如何解析它?
它与命名空间有关吗?
修改 这是有效的代码:
XmlTextReader reader = new XmlTextReader(xmlPath);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(reader);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("ns", xmlDoc.DocumentElement.NamespaceURI);
XmlNode book = xmlDoc.SelectSingleNode("/ns:confirmsubmit/ns:marketingid", nsmgr);
这个XPath比看起来更复杂,我建议像我这样的初学者阅读:http://www.w3schools.com/xpath/xpath_syntax.asp

您需要在游戏中添加XmlNamespaceManager实例:
public class Sample
{
public static void Main()
{
XmlDocument doc = new XmlDocument();
doc.Load("booksort.xml");
//Create an XmlNamespaceManager for resolving namespaces.
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("bk", "urn:samples");
//Select and display the value of all the ISBN attributes.
XmlNodeList nodeList;
XmlElement root = doc.DocumentElement;
nodeList = root.SelectNodes("/bookstore/book/@bk:ISBN", nsmgr);
foreach (XmlNode isbn in nodeList){
Console.WriteLine(isbn.Value);
}
}
}

以下是从Linq到XML的方法。简短
const string xml = @"<confirmsubmit xmlns='http:....'>
<marketingid>-1</marketingid>
</confirmsubmit>";
XElement element = XElement.Parse(xml);
var requestedElement = element.Elements().FirstOrDefault(x => x.Name.LocalName.Equals("marketingid"));

xmlns
属性用于XHTML并定义文档的命名空间。你可以解析它:
XDocument xdoc = XDocument.Load(xmlPath);
var attrib = xdoc.Root.Attribute("xmlns").Value;
