基于元素读取XML节点？

发布于 2024-12-20 15:35:02 字数 770 浏览 0 评论 0原文

我有一个示例 xml

<UserSettings>
   <Source>settings/subscriptions</Source>
   <DestinationController>UserSettings</DestinationController>
   <DestinationAction>GetUserPreferenceSettings</DestinationAction>
</UserSettings>

使用标签名称（UserSettings）读取 XML 的方式如下所示。

XmlDataDocument xmlDoc = new XmlDataDocument();
strFileName = System.Configuration.ConfigurationManager.AppSettings["UrlRoutingPath"].ToString();
strFileLocation = HttpContext.Current.Server.MapPath("~/" + strFileName);

xmlDoc.Load(strFileLocation);

XmlNodeList xmlNode = xmlDoc.GetElementsByTagName("UserSettings");

我如何直接基于元素“Source”读取（例如我上面的xml：通过传递设置/订阅来匹配“Source”元素来读取？）我知道它的真正基础知识，但真的很困惑！

I have a sample xml

<UserSettings>
   <Source>settings/subscriptions</Source>
   <DestinationController>UserSettings</DestinationController>
   <DestinationAction>GetUserPreferenceSettings</DestinationAction>
</UserSettings>

The reading of the XML using tag name(UserSettings) is done as shown below.

XmlDataDocument xmlDoc = new XmlDataDocument();
strFileName = System.Configuration.ConfigurationManager.AppSettings["UrlRoutingPath"].ToString();
strFileLocation = HttpContext.Current.Server.MapPath("~/" + strFileName);

xmlDoc.Load(strFileLocation);

XmlNodeList xmlNode = xmlDoc.GetElementsByTagName("UserSettings");

How do i read directly based on element "Source" ( example for m y above xml : read by passing settings/subscriptions to match the "Source" element ?) I know its real basics, but really confused!

使用Linq-XML（导入System.Xml.Linq命名空间）。

XDocument doc = XDocument.Load(filename);
string value = doc.Root.Element("Source").Value;

Use Linq-XML (import System.Xml.Linq namespace).

XDocument doc = XDocument.Load(filename);
string value = doc.Root.Element("Source").Value;

我会使用 XmlDocument 结合使用SelectSingleNode 接受 XPath 表达式。以下内容未经测试：

XmlDocument doc = new XmlDocument();
strFileName = [...]
doc.Load(strFileName);
sourcetext=doc.SelectSingleNode("/UserSettings/Source").InnerText;

编辑：

这是一个关于如何根据 Source 获取 DestinationController 的粗略示例。

XmlDocument doc = new XmlDocument();
strFileName = [...]
doc.Load(strFileName);
dctext=doc.SelectSingleNode("/UserSettings/[Source=\"Your desired source\"]/DestinationController").InnerText;

I'd use an XmlDocument instead, in combination with SelectSingleNode that accepts an XPath expression. The following is untested:

XmlDocument doc = new XmlDocument();
strFileName = [...]
doc.Load(strFileName);
sourcetext=doc.SelectSingleNode("/UserSettings/Source").InnerText;

Edit:

Here's a rough example on how to get the DestinationController based on Source.

XmlDocument doc = new XmlDocument();
strFileName = [...]
doc.Load(strFileName);
dctext=doc.SelectSingleNode("/UserSettings/[Source=\"Your desired source\"]/DestinationController").InnerText;
