[英]How to get parameter values from an XmlNode in C#
How do I get the values for parameters in a XmlNode tag. 如何获取XmlNode标记中的参数值。 For example:
例如:
<weather time-layout="k-p24h-n7-1">
<name>Weather Type, Coverage, and Intensity</name>
<weather-conditions weather-summary="Mostly Sunny"/>
</weather>
I want to get the value for the parameter 'weather-summary' in the node 'weather-conditions'. 我想在节点'weather-conditions'中获取参数'weather-summary'的值。
var node = xmldoc.SelectSingleNode("weather/weather-conditions");
var attr = node.Attributes["weather-summary"];
In the interest of completeness, the .Net 3.5 way should be given as well: 为了完整性,还应该给出.Net 3.5方式:
Assuming 假设
XDocument doc = XDocument.Parse(@"<weather time-layout='k-p24h-n7-1'>
<name>Weather Type, Coverage, and Intensity</name>
<weather-conditions weather-summary='Mostly Sunny'/></weather>");
Then either 然后
return doc.Element("weather").Element("weather-conditions").Attribute("weather-summary").Value;
Or 要么
return doc.Descendants("weather-conditions").First().Attribute("weather-summary").Value;
Will give you the same answer. 会给你相同的答案。
