C# 解析XML文档

我正在尝试解析来自Amazon AWS的远程XML文档：

我错过了什么？提前谢谢

我正在使用.net 3.5

您使用的是什么版本的.net framework？您可以使用LINQ吗？如果是的话，我会用它来提取这些值，因为这样做会更好一些。关于LINQ的一个非常好的例子，请看这里：

---

Amount不是一个属性，它是一个子元素

相应的xpath查询将是/ItemLookupResponse/Items/Item/ItemAttributes/ListPrice/Amount

---

您没有注意XML文档中的XML名称空间，也没有提供其他答案：

<ItemLookupResponse 
     xmlns="http://webservices.amazon.com/AWSECommerceService/2009-03-31">

更新：如果要浏览ListPrice节点下的子节点，可以执行以下操作：

var curr = ListPrice.Current;

if(ListPrice.MoveNext())
{
    var lpc = ListPrice.Current;

    if(lpc.MoveToFirstChild())
    {
       var node = lpc.Name + "/" + lpc.Value;

       while(lpc.MoveToNext())
       {
           node = lpc.Name + "/" + lpc.Value;
       }
    }
}

---

遍历下的所有子节点并获取它们的名称和值。

我还没有准备好测试工具，所以我不知道这是否适用，但XPath对名称空间也很挑剔。我不知道XPathNavigator是否像代码中预期的那样自动处理默认名称空间。不过，我必须承认，我对xml的深层次细节不是很了解，这是行不通的，因为您没有考虑文档上的xml名称空间！你能在中帮助并编辑正确的版本吗？正如我所说，我对它背后的理论不是很了解。非常感谢。当我在var ListPrice上设置一个断点时——新资产净值。。。。。。通过它，我可以在结果视图集合中看到我需要的数据片段-我如何获得它？

<ItemLookupResponse 
     xmlns="http://webservices.amazon.com/AWSECommerceService/2009-03-31">

XPathDocument Doc = new XPathDocument(@"D:\amazon.xml");

XPathNavigator nav = Doc.CreateNavigator();

// add a XML namespace manager - pick any prefix you want        
XmlNamespaceManager mngr = new XmlNamespaceManager(nav.NameTable);
mngr.AddNamespace("az", "http://webservices.amazon.com/AWSECommerceService/2009-03-31");

// use that XML namespace prefix to select
var ListPrice = nav.Select("/az:ItemLookupResponse/az:Items/az:Item/az:ItemAttributes/az:ListPrice", mngr);

var curr = ListPrice.Current;

if(ListPrice.MoveNext())
{
    var lpc = ListPrice.Current;

    if(lpc.MoveToFirstChild())
    {
       var node = lpc.Name + "/" + lpc.Value;

       while(lpc.MoveToNext())
       {
           node = lpc.Name + "/" + lpc.Value;
       }
    }
}
