“空”是XML命名空间的有效值吗?如果是,这是什么意思?
我有以下XML代码,但我不知道Field1和Field2元素属于哪个命名空间。
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header /> <soap:Body> <Root xmlns="uri"> <Field1 xmlns="">147079737</Field1> <Field2 xmlns="">POL</Field2> </Root> </soap:Body> </soapenv:Envelope>
是的,它是有效的。
Section 6.2在
Namespaces in XML 1.0 Recommendation专门说:
原文链接:https://www.f2er.com/xml/293422.htmlThe attribute value in a default namespace declaration MAY be empty. This has the same effect,within the scope of the declaration,of there being no default namespace.
引用自评论:
It is legal,and this is the way to bring an element into the global namespace.
