既然您说您使用 c# 2.0(因此不能使用 LINQ-to-XML),那么从 XML 中查找单个值的最简单方法就是使用 XPath:
由于您的 XML 包含命名空间
,因此问题变得更加复杂:您需要初始化XmlNamespaceManager
并将其传递给>XPathNavigator
。这是一篇博客文章,详细解释了这个问题;还可以在 XmlNode.SelectNodes MSDN 页面上找到示例(请参阅上面的链接)。Since you said that you use c# 2.0 (and, thus, cannot use LINQ-to-XML), the easiest way to just find single values out of your XML would be to use XPath:
Since your XML contains namespaces
<v9:...>
, the issue gets a bit more complicated: You need to initialize anXmlNamespaceManager
and pass it to theXPathNavigator
. Here is a blog post that explains this issue in detail; an example can also be found at the XmlNode.SelectNodes MSDN page (see link above).
