An XML template has a Header section and a Detail section, separated graphically by a line across the tree view.
The items in the Header section are generated only once when the report is exported to XML, unless the report is a group report. For group reports, you can choose to generate the contents of the header section iteratively for each group. For more information, see “Generating group headers”.
The Detail section contains the row data, and is generated iteratively for each row in the report.
A line across the Export/Import Template view separates the Header section from the Detail section. The first element after this line, d_dept_list_row in the previous screenshot, is called the Detail Start element.
There can be only one Detail Start element, and it must be inside the document’s root element. By default, the first child of the root element is the Detail Start element. It usually wraps a whole row, separating columns across rows. When the report is exported to XML, this element and all children and/or siblings after it are generated iteratively for each row. Any elements in the root element above the separator line are generated only once, unless the report is a group report and the Iterate Group Headers check box has been selected.
The Detail Start element can be a nested (or multiply-nested) child of an element from the Header section, permitting a nested detail.
You can change the location of the separator line by selecting the element that you want as the Detail Start element and selecting Starts Detail from its pop-up menu. The separator line is redrawn above the new Detail Start element. When you export the data, the Detail Start element and the children and siblings after it are generated iteratively for each row.
If no Detail Start element is specified (that is, if the Starts Detail option has been deselected), the template has only a Header section. When you export the data, only one iteration of row data is generated.
