DomDocument->create_element_ns — Create new element node with an associated namespace
This function returns a new instance of class DomElement. The tag name of the element is the value of the passed parameter name . The URI of the namespace is the value of the passed parameter uri . If there is already a namespace declaration with the same uri in the root-node of the document, the prefix of this is taken, otherwise it will take the one provided in the optional parameter prefix or generate a random one. 本节点不会出现在文档中，除非是用例如 domnode_append_child() 函数来将其插入。
The return value is FALSE if an error occurred.
