Comments Tab
The Comments tab is common to all tasks. It contains a single text area (Task comments)that
lets you write comments about the task. These comments are saved when the dialog is closed
with the OKbutton, and are displayed in the Task Comments Pane.
New Wild Card
Since all metadata data pages, and possibly all physical data pages, are treated by the task at
run-time in order to evaluate the condition at each level, it is necessary to dynamically define
metadata as well as data selections to check all occurrences instead of a fixed one. To
accommodate this requirement, a syntax modification is introduced in all current data and
metadata functions (region(), @(), field(), xmlget()). The parameter identifying the data page or
the level can now be replaced with a question mark (“?”), indicating that a dynamic update of
the current data page or level is required before evaluating the condition.
For example, in a PDF emulation, the format of a selected region would look like this:
region(?,0.59375,2.21875,1.85416,2.51041,KeepCase,NoTrim)
where "?" represents the current page. Using this expression, if the metadata structure has 3
data pages, then the task willproceed 3 times sequentially, with ?=1 for the first data page, ?=2
for the second and ?=3 for the third and last data page index from the metadata structure.
In the Metadata tab of the Data Selector, the syntax of the selection is:
GetMeta(ItemDesc[?], 2, Job.Group[?].Document[?].Datapage[?])
where "?" is replaced with the current level index.
Note: For a relative position, the string has to be edited manually.
Use Case
Given a document input (created with metadata), this task can be used to regroup the PDF
pages of the received print stream in logical (metadata) documents, based on the keyword
“Page 1 of” printed on the pages, and then, treat each newly created document individually in
the rest of the process
The process begins with the following tasks:
