c#中的XML -为新的XML元素添加命名空间

本文关键字：XML 元素 添加 命名空间 中的 | 更新日期: 2023-09-27 17:53:05

我发布的XML可能很大，但我的问题相当简单。请看看第二次元标签。第一个维度是自动生成的。第二个是我在c#脚本中创建的。问题是:如何使我的Dimension标签具有与生成的名称空间完全相同的名称空间("xsi:type="RegularMeasureGroupDimension")?谢谢你的帮助!

这是我用来生成Dimension的c#代码: 
XmlNode dimensions2 = doc.DocumentElement.ChildNodes[1].ChildNodes[0].ChildNodes[6].ChildNodes[0].ChildNodes[5];
            dimensions2.AppendChild(dimension2);
        //dimension2.SetAttribute("xmlns","http://schemas.microsoft.com/analysisservices/2003/engine");
           // dimension2.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XmlSchema-instance");
            dimension2.SetAttribute("type", "http://www.w3.org/2001/XmlSchema-instance", "RegularMeasureGroupDimension");

这是XML文件:

    <DatabaseID>test_szymon</DatabaseID>
  </ParentObject>

c#中的XML -为新的XML元素添加命名空间

您可以尝试使用XmlDocument.CreateAttribute(prefix, localName, namespaceURI)方法，它允许我们指定属性的前缀，例如:

var attr = doc.CreateAttribute("xsi", "type", "http://www.w3.org/2001/XmlSchema-instance");
attr.Value = "RegularMeasureGroupDimension";
dimension2.SetAttributeNode(attr);
