After opening a sample of the data (see "Choosing a sample data file" on page72) and/or
Metadata, you can easily make a selection.
It is also possible to manually enter a data selection, or to change it after making a selection
with the mouse pointer.
Data selections can also be used in a PlanetPress Design document that is being merged with
the data (for example in a printed output); for more information, see PlanetPress Design User
Guide.
Wild card parameter "?"
Data/Metadata selection functions accept a wildcard parameter "?", indicating the function
operates on all nodes (not just one) of a given level.
Examples
l
In a PDF emulation, the format of a selected region could be:
region(?,0.59375,2.21875,1.85416,2.51041,KeepCase,NoTrim)
In this case “?” represents the current physical data page processed by the task.
l
In the following rule, the Metadata selection function loops through all datapages in a job,
comparing their index in the document to a value:
(GetMeta(SelectedIndexInDocument[0], 11, Job.Group[?].Document
[?].Datapage[?]) Equal 0
l
In the following rule, the question mark in the text-based data selection represents the
current page number:
(@(?,1,1,1,9,KeepCase,NoTrim) IS EQUAL TO Page 1 of)
Text-based data selections
Text-based selections are used for text data files such as Line Printer, ASCII and Channel Skip
emulations. The selection refers to a rectangular selection that may contain multiple lines, rows,
columns on a given page.
