                                                  bcl_716964462.htm

                                                  9. The two columns example

                                                  The example tasksTwoColumns shows how to use Xpath to create a two columns report using a linear input XML file. The output will look like this:



                                                  It is a list of tasks organized in 2 columns, with the task name and the employee assign to the task.

                                                  The layout of the report is:

                                                  • there is a detail area which will contain 2 task name fields (2 columns). Therefore the area will need to be repeated for every second task. The Xpath to achieve this is:

                                                    ROWSET/ROW[position() mod 2 = 1]

                                                    This will select every second „ROW“ element in the XML
                                                  • In the area there are 2 TaskName field. The Xpath of the fields are:
                                                    • TASK_NAME : to select the TASK_NAME field in the current ROW node
                                                    • TASK_NAME/../following-sibling::ROW/TASK_NAME: to select the TASK_NAME field in the next ROW after the currently selected ROW (this will be the second column)

                                                      the XPATH expression means:
                                                      • select current TASK_NAME
                                                      • use the /../ to select the parent node (the ROW node)
                                                      • following-sibling::ROW: will select the next ROW
                                                      • /TASK_NAME selects the field in the ROW
