Question

我在我的网络应用程序中使用AWS。我得到了WS响应。

Xml回复：

 <ItemSearchRespone xmlns="http:/....">
  <Items>
   <Item>
  <ASIN>B003MC5N28</ASIN>

  **</ItemAttributes>**
  </Item>
  <Item>  another item list2</Item>
  <Item>  another item list<3.../Item>
 </Items>
  </ItemSearchResponse>

在这里，我想在网格视图中显示所有书籍的所有标题值和格式化价格。

到目前为止我已经尝试过了。

        XmlDocument xdoc = new XmlDocument();
        xdoc.Load(response.GetResponseStream());
        XmlNamespaceManager ns = new XmlNamespaceManager(xdoc.NameTable);
        ns.AddNamespace("ms", "http://webservices.amazon.com/AWSECommerceService/2005-10-05");

        XmlNodeList xnl = xdoc.SelectNodes("//ms:Title", ns);
        XmlNodeList xnl1 = xdoc.SelectNodes("//ms:FormattedPrice", ns);



        DataTable dt=new DataTable();
        dt.Columns.Add("Title",typeof(string));
        dt.Columns.Add("Price", typeof(string));

        foreach (XmlNode Title in xnl)
        {
            DataRow dr = dt.NewRow();
            dr["Title"] = Title.InnerText;

            dt.Rows.Add(dr);
        }
        GridView1.DataSource = dt;
        GridView1.DataBind();

如何在网格视图中显示价格和标题值？（Respone有很多节点，如title，Price，isbn等等。如果您需要更多信息，请告诉我。

感谢。

LINQ to XML解析XML文档。

XNamespace ns = "http://webservices.amazon.com/AWSECommerceService/2005-10-05";
XDocument doc=XDocument.Load(response.GetResponseStream());

var result= doc.Descendants(ns + "ItemAttributes").Select( p=> new 
 {
 Title=p.Element(ns+ "Title").Value,
 Price = p.Element(ns +"ListPrice").Element(ns+"FormattedPrice").Value
}).ToList();
GridView1.DataSource = result;
GridView1.DataBind();

或更改XPath表达式，

 XmlNodeList xnl = xdoc.SelectNodes("/ms:ItemSearchRespone/ms:Items/ms:Item/ms:ItemAttributes", ns);

  foreach (XmlNode ele in xnl)
   {
     Console.WriteLine(ele.SelectSingleNode("ms:Title", ns).InnerText);
     Console.WriteLine(ele.SelectSingleNode("ms:ListPrice/ms:FormattedPrice", ns).InnerText);
   }

如何在网格视图中显示（WS响应）的xmlnode值？
