为了使专有的 Parse() 函数正常工作，我在从文档中删除命名空间时遇到了一些麻烦。我收到一个如下所示的 XML 字符串：

这是我需要 XML 的格式，以便引用的Parse()函数正确解析数据。但是，我似乎无法让它在代码中工作。我已经尝试过这里描述的解决方案：如何删除命名空间前缀。(C#)但是当我调用Remove()方法时，s:前缀会转换为p:7.

有人可以给我一些关于如何将我的第一个示例转换为我的第二个示例的建议。

编辑：这是我现在拥有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

您的问题是您正在从根元素中删除名称空间前缀，但它仍被用于限定文档其余部分中的属性本身。您想首先从整个文档中去除名称空间。

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\\"));

这将产生您所追求的 XML。
