AppleScript: PDF Formularfelder befüllen

Folgendes kleines AppleScript wurde inspiriert durch ein PHP Script.

Ein mit Formularfeldern pröpariertes PDF wird als Vorlage benutzt. Die Formularfelder die als Wert bzw. Standardtext einen Platzhalter enthalten werden durch suchen/ersetzen mit Werten befüllt.

Dieses PDF kann einfach mit den Formularfunktionen von OpenOffice erstellt werden. Hier ist die OO Beispieldatei zu finden.

Einfach und genial. Ein Ansatz mit Potenzial ;-)

(*
pdf_form_fill.applescript
This applescript was inspired by the php script pdf_form_fill from @author Lars Wegmann info@wegmann-it.de
The script replaces the values of the form textfield in a pdf file. 
For example:
Make a new OpenOffice Writer document, insert some form textfields. 
The value of the fields represents the placeholders that would be 
replaced later with applescript.
Notice:
The placeholder it self must have the lenght of the maxlength of the form textfield. If the
textfield has 40 characters the placeholder must have also 40 characters.
The replace string can't be longer than the search string (the placeholder).
