XML 元素未绑定

Question

我收到了要导入 ADFS 的元数据文件，但我一直收到错误消息：4:108 元素 "md:EntityDescriptor" 的前缀 "md" 未绑定。

我看了文档，在网上到处搜索，仍然找不到适合我的答案。这是删除了证书和联系信息的示例代码：

<md:EntityDescriptor ID="_63bb4679460ce67f883efc407ff14172e3472007" entityID="https://1502.censis.net/sso">

Answer 1

None 的命名空间前缀绑定到命名空间 uri。如果您将 "md" 绑定到一个 uri（如 xmlns:md="md namespace uri"），您会收到 "alg" 未绑定的错误。

来自规范 (4 Qualified Names)：

The Prefix provides the namespace prefix part of the qualified name, and MUST be associated with a namespace URI reference in a namespace declaration.

规范中有更多信息：https://www.w3.org/TR/xml-names/

如果您从其他人那里收到此 XML，您应该让他们知道 XML 格式不正确。
