Question

我在从文档中删除命名空间时遇到一些麻烦，以便专有的Parse（）函数正常工作。我收到的XML字符串如下所示：

<r xmlns:p="p" xmlns:s="s" p:p="1">

我正在使用编辑实用程序以HTML格式查看上述XML，该输出显示相同的输出：

这是我需要XML来引入Parse()函数来正确解析数据的格式。但是我似乎无法在代码中使用它。我尝试过此处描述的解决方案：How to remove namespace prefix. (C#)但是当我调用Remove()方法时，s:前缀会转换为类似p:7的内容。

有人可以就如何将我的第一个例子转换为第二个例子给我一些建议。

编辑：这是我现在的代码和我得到的输出

XDocument xDoc = XDocument.Parse(renderingProperty);
xDoc.Root.RemoveAttributes();
xDoc.Root.Add(new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance\\"));
xDoc.Root.Add(new XAttribute(XNamespace.Xmlns + "xsd", "http://www.w3.org/2001/XMLSchema\\"));

输出

您的问题是您要从根元素中删除命名空间前缀，但它仍然用于在文档的其余部分中限定属性本身。您希望首先从整个文档中删除命名空间。

public static class XmlExtensions
{
    public static void StripNamespace(this XDocument document)
    {
        if (document.Root == null) return;

        foreach (var element in document.Root.DescendantsAndSelf())
        {
            element.Name = element.Name.LocalName;
            element.ReplaceAttributes(GetAttributesWithoutNamespace(element));
        }
    }

    static IEnumerable GetAttributesWithoutNamespace(XElement xElement)
    {
        return xElement.Attributes()
            .Where(x => !x.IsNamespaceDeclaration)
            .Select(x => new XAttribute(x.Name.LocalName, x.Value));
    }
}

然后简单地说：

XDocument xDoc = XDocument.Parse(xml);
xDoc.StripNamespace();
xDoc.Root.Add(new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance\\"));
xDoc.Root.Add(new XAttribute(XNamespace.Xmlns + "xsd", "http://www.w3.org/2001/XMLSchema\\"));

这会生成您所使用的XML。
