CHAPTER 12 Exporting and Importing XML Data
Users Guide 379
For each attribute specified, you can select a control reference from the
drop-down list or enter a literal text value. A literal text value takes precedence
over a control reference. You can also use the expression button to the right of
the Text box to enter an expression.
The expression button and entry operates similarly to report properties in the
Properties view. The button shows an equals sign if an expression has been
entered, and a not-equals sign if not. A control reference or text value specified
in addition to the expression is treated as a default value. In the template, this
combination is stored with the control reference or text value, followed by a
tab, preceding the expression. For example:
attribute_name=~"text_val~~tdw_expression~"
Composite and nested reports
Report controls can be referenced in the Detail section of export templates as
children of an element.
Nested reports supported for XML export only
Import does not support nested reports. If you attempt to import data in any
format, including XML, CSV, DBF, and TXT, that contains a nested report, the
nested report is not imported and the import may fail with errors.
