C# 解析xml文件(带命名空间 xmlns和 xmlns:xsi)

 1、带有命名空间 并且命名空间后带 xmlns:xsi =" "

1 <?xml version="1.0" encoding="utf-8" ?>
 2 <SendExResp xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"  xmlns="urn:schemas-microsoft-com:office:spreadsheet">
 3   <PayCount>1</PayCount>
 4   <BlackWords />
 5   <ErrorMobiles />
 6   <BlackMobiles />
 7   <BatchSendID>00000000-0000-0000-0000-000000000000</BatchSendID>
 8   <Result>
 9     <name>王麻子</name>
 10  </Result>
 11 <ErrorDesc>成功</ErrorDesc>
12</SendExResp>

 

解析：

String path = System.AppDomain.CurrentDomain.BaseDirectory + "//return.xml";
 
            XmlDocument xmldoc = new XmlDocument();
            xmldoc.Load(path);
 
            XmlNamespaceManager namespaceManager = new XmlNamespaceManager(xmldoc.NameTable); //namespace 
            namespaceManager.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
            namespaceManager.AddNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
            namespaceManager.AddNamespace("d","urn:schemas-microsoft-com:office:spreadsheet");
            XmlNode node = xmldoc.SelectSingleNode("descendant::d:Result/d:name", namespaceManager);
 
            string name= string.empty;
            if (node != null)
            {
                 name = node.InnerText;
            }

               Conosle.WriteLine("name:"+ name)；
               Conosle.ReadKey();

         运行结果： name：王麻子 

 

 

2、带有命名空间 不带前缀 xmlns=" "

<?xml version='1.0'?>
<bookstore xmlns="urn:newbooks-schema">
  <book genre="novel" style="hardcover">
    <title>The Handmaid's Tale</title>
    <author>
      <first-name>Margaret</first-name>
      <last-name>Atwood</last-name>
    </author>
    <price>19.95</price>
  </book>
  <book genre="novel" style="other">
    <title>The Poisonwood Bible</title>
    <author>
      <first-name>Barbara</first-name>
      <last-name>Kingsolver</last-name>
    </author>
    <price>11.99</price>
  </book>
</bookstore>

解析：

public static void Main()
  {
 
      XmlDocument doc = new XmlDocument();
      doc.Load("newbooks.xml");
 
      // Create an XmlNamespaceManager to resolve the default namespace.
      XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
      nsmgr.AddNamespace("bk", "urn:newbooks-schema");
 
      // Select the first book written by an author whose last name is Atwood.
      XmlNode book;
      XmlElement root = doc.DocumentElement;
     book = root.SelectSingleNode("descendant::bk:book[bk:author/bk:last-name='Atwood']", nsmgr);
 
      Console.WriteLine(book.OuterXml);
 
  }
