|  | [Add](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_XmpData_Add_2_df764941.htm.md) | Adds a node to the top of the XMP tree. |
|  | [AddNode](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_XmpData_AddNode_1_79cf5b78.htm.md) | Adds a node to the XMP tree. |
|  | [Clear](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_XmpData_Clear.htm.md) | Sets all elements in the array to zero, to **false**, or to a null reference (**Nothing** in Visual Basic), depending on the element type. |
|  | [Contains](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_XmpData_Contains_1_d02429b3.htm.md) | Determines whether a node is in the tree. |
