在xml文件中添加更多部分 [英] Adding More sections in an xml file

问题描述

我正在创建一个xml文件来保存GUI值。我使用configurationManager和appSettings方法来创建文件。我能够创建如下的xml文件

 <  配置 >  
 <   appsettings  >  
 <   add     key   =  A1   值  =  10000    /  >  
 <   add     key   =  A2    value   =  10000    /  >  
 <   add     key   =  A3    value   =  10000     /  >  
 ...... 
 <   / appsettings  >  
 <   / configuration  >  

但是我想在xml中添加如下所示的更清晰的部分

 <   configa  >  
 <！ -     Config1    - >   
 <   add     key   =  A1   值  =  10000    /  >  
 <！ -     Config2    - >   
 <   add     key   =  A1     value   = < span class =code-keyword> 10000    /  >  
 <！ -     Config3    - >   
 <   add     key   =   A1    value   =  10000    /  >  
 <   / configa  >  
 <  < span class =code-leadattribute> configb  >  
 <！ -     ConfigB1    - >   
 <   add     key   =  B1 < span class =code-attribute>   value   =  10000    /  > ;  
 <！ -     ConfigB2    - >   
 <   add     key   =   B1    value   =  10000    /  >  
 <！ -   < span class =code-keyword>  ConfigB3    - >   
 <   add     key   =  B1    value   =  10000    /  >  
 <   / configb  >  

如何实现这一目标？请建议。

解决方案

最好不要直接执行XML操作值，而是使用序列化：https://en.wikipedia.org/wiki/Serialization [ ^ ]。



最强大，最先进且最易于使用的序列化基于数据合同： http://msdn.microsoft.com/en-us/library/ms733127。 aspx [ ^ ]。

如果您仍需要保持较低级别，.NET FCL提供了不同的解析方式和生成XML。这是我对它们的简短概述：

1. 使用 System.Xml.XmlDocument 类。它实现了DOM接口;如果文档的大小不是太大，这种方式是最简单和最好的。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx 。
2. 使用类 System.Xml .XmlTextWriter 和 System.Xml.XmlTextReader ;这是最快的阅读方式，特别是你需要跳过一些数据。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.aspx ， http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx 。
3. 使用类 System.Xml.Linq.XDocument ;这是类似于 XmlDocument 的最合适的方式，支持LINQ to XML Programming。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx ，http://msdn.microsoft.com/en-us/library/bb387063.aspx 。

Hi,

I am creating an xml file to save the GUI values. I used the configurationManager and appSettings approach to create the file. I am able to create the xml file as below

<configuration>
	<appsettings>
		<add key="A1" value="10000" />
                <add key="A2" value="10000" />
                <add key="A3" value="10000" />
......
	</appsettings>
</configuration>

But I want to add more clear sections like as below in the xml

<configa> 
            <!-- Config1 -->
		<add key="A1" value="10000" />
            <!-- Config2 -->
		<add key="A1" value="10000" />
            <!-- Config3 -->
		<add key="A1" value="10000" />
</configa>
<configb> 
            <!-- ConfigB1 -->
		<add key="B1" value="10000" />
            <!-- ConfigB2 -->
		<add key="B1" value="10000" />
            <!-- ConfigB3 -->
		<add key="B1" value="10000" />
</configb>

How do I achieve this? Please suggest.

解决方案

Better don't do XML manipulation values directly, use serialization instead: https://en.wikipedia.org/wiki/Serialization[^].

Most robust, advanced and yet easiest to use serialization is based on Data Contract: http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

For further detail, please see my past answers:
how to pass a datacontract from a C#/WCF code to Managed C++[^],
How can I utilize XML File streamwriter and reader in my form application?[^],
Creating property files...[^].

If you still need to stay on lower level, .NET FCL offers different ways for parsing and generating XML. This is my short overview of them:

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx.
2. Use the classes System.Xml.XmlTextWriter and System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.aspx, http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx.
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx, http://msdn.microsoft.com/en-us/library/bb387063.aspx.
