问题描述

< employee>

< employee>

< id> 1

< userid> arvind

< password> 123456

< isactive> false



< employee>

< ; id> 2

< userid> tarun

< password> 123

< isactive> false

<employee>
<employee>
<id>1
<userid>arvind
<password>123456
<isactive>false

<employee>
<id>2
<userid>tarun
<password>123
<isactive>false

推荐答案

string xmlstr = @"<employees>
  <employee>
    <id>1</id>
    <userid>arvind</userid>
    <Password>123456</Password>
    <isactive>false</isactive>
  </employee>
  <employee>
    <id>2</id>
    <userid>tarun</userid>
    <Password>123</Password>
    <isactive>false</isactive>
  </employee>
</employees>";

XmlDocument document = new XmlDocument();
document.LoadXml(xmlstr);

XmlNode employee = document.SelectSingleNode("//employee[id='2']");
employee["Password"].InnerText = "newpass";

请注意以下几点：

- 我想你必须从文件加载（使用正确的方法）

- 我选择了员工ID = 2

- 我使用 employee s 作为根元素.Yous根元素也是员工。

- 这是内存更新，您可能需要保存结果

Please note followings:
- I suppose you will have to load from file (use proper method)
- I have selected the Employee with ID=2
- I have used employees as root element. Yous root element was also employee.
- This was an in-memory update, you will probably have to save the result
