一个人能否解释一下,在XML中究竟究竟是什么名称空间(xmlns=......)以及这些空间在使用E4X(在行动第三号)验证XML时如何使用?
I fail to fully understand their purpose and usage.
In theory, XML namespaces are used to avoid conflict with tag names. So I can create a namespace that contains a tag named "mytag" and someone else creates a different namespace with the same tag "mytag" and there won t be any conflict. Each "mytag" tag will be clearly differentiated.
在实践中,我发现,XML名称空间非常无用(你常常有两家开发商为同一XML档案制造标签?),而且只是使该区变得难以想象。
在EX4中,你需要获得名字空间,然后把每个帽子贴上这个名称空间。 因此,例如,如果你想要进入标签<somenamespace:somename>。 页: 1
var somenamespace:Namespace = xml.namespace("somenamespace");
var sometag:XML = somenamespace::somename[0];
如果你在谷歌上搜索,你会发现一些AS3级,将这些无用名称空间从XML中删除,使之更容易地平息。
