c# 2.0 -在c# 2.0中解析XML片段中的三个特定元素

本文关键字：三个 元素 片段 XML | 更新日期: 2023-09-27 18:01:18

如何使用c# 2.0从我的XML解析几个标签的值?

我想解析标签和它们的值，比如

1) <v9:Severity>SUCCESS</v9:Severity>

2) <v9:TrackingNumber>634649515000016</v9:TrackingNumber>

3) <v9:Image>iVBORw0KGgoAAAANSUhEUgAAAyAAAASwAQAAAAAryhMIAAAagEl</v9:Image>

如何用c# 2.0以编程方式获得上述元素的值?

c# 2.0 -在c# 2.0中解析XML片段中的三个特定元素

既然您说使用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:

  • 可以使用XPathNavigator (MSDN: Select XML Data using XPathNavigator)
  • 或者您可以使用XmlNode。直接SelectNodes。

由于XML包含名称空间<v9:...>，因此问题变得有点复杂:需要初始化XmlNamespaceManager并将其传递给XPathNavigator。这里有一篇博客文章详细解释了这个问题;在XmlNode中也可以找到一个示例。选择节点MSDN页面(见上面的链接)。

  • 使用XPathNavigator查询带有名称空间的XML
