如何在 c# .net CF 3.5 中使用 XmlDocument 向 xml 添加属性 [英] How to add attributes to xml using XmlDocument in c# .net CF 3.5

问题描述

我需要为元素aaa"创建一个带有前缀xx"的属性abc".以下代码添加了前缀，但它也将 namespaceUri 添加到元素.

I need to create an attribute "abc" with the prefix "xx" for an element "aaa". The following code adds the prefix but it also adds the namespaceUri to the element.

所需输出:

<mybody>
<aaa xx:abc="ddd"/>
<mybody/>

我的代码:

  XmlNode node = doc.SelectSingleNode("//mybody");
  XmlElement ele = doc.CreateElement("aaa");

  XmlAttribute newAttribute = doc.CreateAttribute("xx","abc",namespace);              
  newAttribute.Value = "ddd";

  ele.Attributes.Append(newAttribute);

  node.InsertBefore(ele, node.LastChild);

以上代码生成:

<mybody>
<aaa xx:abc="ddd" xmlns:xx="http://www.w3.org/1999/XSL/Transform"/>
<mybody/>

想要的输出是

<mybody>
<aaa xx:abc="ddd"/>
<mybody/>

并且xx"属性的声明应该在根节点中完成，如:

And the declaration of the "xx" attribute should be done in the root node like :

<ns:somexml xx:xsi="http://www.w3.org/1999/XSL/Transform"  xmlns:ns="http://x.y.z.com/Protocol/v1.0">

如果以 deisred 格式获得输出，如何获得?如果 xml 不是这种所需的格式，则无法再对其进行处理..

How can if get the output in the deisred format? If the xml is not in this desired format then it cannot be processed anymore..

谁能帮忙?

谢谢，维姬

推荐答案

相信直接在根节点上设置相关属性就可以了.这是一个示例程序:

I believe it's just a matter of setting the relevant attribute directly on the root node. Here's a sample program:

using System;
using System.Globalization;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement root = doc.CreateElement("root");

        string ns = "http://sample/namespace";
        XmlAttribute nsAttribute = doc.CreateAttribute("xmlns", "xx",
            "http://www.w3.org/2000/xmlns/");
        nsAttribute.Value = ns;
        root.Attributes.Append(nsAttribute);

        doc.AppendChild(root);
        XmlElement child = doc.CreateElement("child");
        root.AppendChild(child);
        XmlAttribute newAttribute = doc.CreateAttribute("xx","abc", ns);
        newAttribute.Value = "ddd";        
        child.Attributes.Append(newAttribute);

        doc.Save(Console.Out);
    }
}

输出:

<?xml version="1.0" encoding="ibm850"?>
<root xmlns:xx="http://sample/namespace">
  <child xx:abc="ddd" />
</root>
