Does anybody know what is going to be the support of namespaces in ExtJS 3.0?
It is ridiculous to develop an internet based business application without support of SOAP services. So fullfeatured XML opearation API is a must. JSON is a kindergarden technology for transporting business data. If ExtJs aims to follow RIA requirements it must deal with XMLs.
Till the moment this becomes a fact, as SMAIL points, the client-side conversion is the only way.
This approach lets you search for names with namespace prefixes, but not namespaces. Throughout a document the same namespace can be used with different prefixes. The DOM API should be level 2 and for the additional selector-based query functions it should be possible to declare the prefixes for the namespaces that will be used in the selectors. Those prefixes are not related to those in the XML document.
