The RemoveChild(xmlTree, child) command removes the child node child from the XML element xmlTree. All children equal to the specified child are removed unless the child argument is a positive integer less than or equal to the number of children of the tree. (The positive integer is taken to represent the position of a child and only that child node is removed.)

Note: The input XML tree is not modified; a copy of the tree is returned with the indicated child removed.
