C＃4.0：删除XML文件的所有节点 [英] C#4.0: To delete all nodes of an XML file

问题描述

Hello

我有一个XML文件：

<？xml version =" 1.0" ;编码= QUOT; UTF-8英寸？> 
  - < dataroot xmlns：od =" urn：schemas-microsoft-com：officedata"的xmlns：的xsi = QUOT; HTTP：//www.w3.org/2001/XMLSchema-instance"的xsi：noNamespaceSchemaLocation = QUOT; Test.xsd"产生= QUOT; 2016-09-16T22：06：41"> 
  - < Table2> 
< ID> 1< / ID> 
< Name> A< / Name> 
< / Table2> 
  - < Table2> 
< ID> 2< / ID> 
< Name> B< / Name> 
< / Table2> 
< / dataroot> 

我想删除所有节点。

解决方案

我写了这段代码。这有效：

 XmlDocument xmlDoc = new XmlDocument（）; 
 xmlDoc.Load（Application.StartupPath + @" \ Table1.xml"）; 
 XmlElement xmlRoot = xmlDoc.DocumentElement; 
 XmlNodeList Types = xmlRoot.ChildNodes; 
 int countTypes = Types.Count; 
 int index = 0; 
 while（index< countTypes）
 {
 XmlNode nodelist = xmlDoc.SelectSingleNode（" / dataroot / Table1 [ID ='" +（index + 1）.ToString（）+ "']"）; 
 nodelist.ParentNode.RemoveChild（nodelist）; 
 index ++; 
} 
 xmlDoc.Save（Application.StartupPath + @" \ Table1.xml"）; 

Hello

I have an XML file:

 <?xml version="1.0" encoding="UTF-8" ?> 
- <dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Test.xsd" generated="2016-09-16T22:06:41">
- <Table2>
  <ID>1</ID> 
  <Name>A</Name> 
  </Table2>
- <Table2>
  <ID>2</ID> 
  <Name>B</Name> 
  </Table2>
  </dataroot>

I want to delete all of nodes.

解决方案

I wrote this code. This works weel:

                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(Application.StartupPath + @"\Table1.xml");
                XmlElement xmlRoot = xmlDoc.DocumentElement;
                XmlNodeList Types = xmlRoot.ChildNodes;
                int countTypes = Types.Count;
                int index = 0;
                while (index < countTypes)
                {
                    XmlNode nodelist = xmlDoc.SelectSingleNode("/dataroot/Table1[ID='" + (index + 1).ToString() + "']");
                    nodelist.ParentNode.RemoveChild(nodelist);
                    index++;
                }
                xmlDoc.Save(Application.StartupPath + @"\Table1.xml");
