This method reads a XML-file and puts the nodes, attributes and values in the output temp-table. If you supply the starting node name it will only read the nodes that have this name and its child nodes.
Parameters
| icXMLFile | input | character | Filename of the XMLfile that will be used to fill the output temp-table. |
