Hi,
Could someone clarify part of the XML Namespaces spec for me?
The spec states that namespace declarations are a special category of
attribute: "A namespace is *declared* using a family of reserved
attributes. Such an attribute's name must either be |xmlns| or have
|xmlns:| as a prefix".
So if a namespace declaration like
xmlns:foo="http://www.foo.com/some.namespace"; is made, and that
declaration is considered a type of attribute, then:
- the namespace prefix of the attribute is "xmlns"
- the local name of the attribute is "foo"
- the value of the attribute is "http://www.foo.com/some.namespace";
But what is the namespace URI of the attribute? What namespace does the
prefix "xmlns" belong to?
And then you have default namespace declarations, such as
xmlns="http://www.foo.com/some.namespace";.
- the namespace prefix of the attribute is an empty string: ''
- the local name of the attribute is "xmlns"
- the value of the attribute is "http://www.foo.com/some.namespace";
And I presume in this case, the namespace URI would be an empty string?
I'm asking because I'm unsure how a DOM method like getAttributeNS is
supposed to deal with namespace declarations. Would xmlns attributes
simply be ignored in this case?
