如何使用Xpath读取属性值 [英] how to read attribute value using Xpath

问题描述

请告诉我如何从下面的xml读取属性值"process1"和"process2"，请帮帮我:

Hi,
Please tell me how to read attributes values "process1" and "process2" from the below xml please help me out:

<package>
  <workflowprocesses>
    <workflowprocess name="process1">
    </workflowprocess>
    <workflowprocess id="hj21-b3jkj" name="process2">
      <activites>
          <activity>
             <version>1.0.0.0</version>
          </activity>
      </activites>
    </workflowprocess>
  </workflowprocesses>
</package>

推荐答案

XmlNodeList elemList = doc.GetElementsByTagName("workflowprocess");     
for (int i = 0; i < elemList.Count; i++)     
{         
  string attrVal = elemList[i].Attributes["name"].Value;     
}

string attrVal = doc.SelectSingleNode("/workflowprocess/@name").Value;

在C#中读取/写入XML [

Have a look at this link;

Read / Write XML in C#[^]

Good luck.

使用LINQ to XML解析您的xml文档.这里是一个示例.

Use LINQ to XML to parse your xml document.Here is an example.Language-Integrated Query for XML Data[^]

这是您的Xpath:

/package/workflowprocesses/workflowprocess [@name =''process2'']/activites/activity/version

here is your Xpath:

/package/workflowprocesses/workflowprocess[@name=''process2'']/activites/activity/version
