Xmlns = ""

Using dom4j to combine the elements in the two hands, dom4j will write xmlns = "" on the added elements. At that time, I did not care about it. Later, the user asked me to remove it, it is not that easy to check. In the past, XML itself had very strict namespace management. If the namespace of the two elements is different, and the latter has no namespace, that is, the default value is "". once added, it will be explicitly written out and cannot be changed. I understand it. However, the customer does not agree, mainly because it does not look good and has to be changed,

Root. addelement (child) -->
Root. addelement (***. parsetext ('<tmproot xmlns = "rootsnamespace">' + child. asxml () + '</tmproot> '). getrootelement. element ('child ')))
