I'm trying to combine various xmls into single xml piece , while doing so I want to exclude certain elements ex: ``` <root> <mono> ...... ... </mono> <view> </view> <mono> </mono> </root> ``` I just want the monos result: ``` <mono> </mono> <mono> </mono> ``` I cannot go in each xml and set combine.self= remove for the element view. how to achieve this?
