◆ addElement()

QString XmlElementCollection::addElement ( ElementsLocation & location )

XmlElementCollection::addElement Add the element at location to this collection. The element is copied in this collection in "import" dir with the same path, in other word if the path is dir1/dir2/dir3/myElement.elmt, myElement is copied to this collection at the path : import/dir1/dir2/dir3/myElement.elmt If the path doesn't exist, he was created. If the element already exist, do nothing.

Parameters

location : location of the element

Returns: the collection path of the added item or a null QString if element can't be added.
