(DOORS/DXL) Export to pdf or print with a given template

Question

We are interested in export/print one view from formal module. As we want it can be an ofcial document we want to add our corporative template that have it own front page, a

Answer 1

Is it possible made it by a DXL script?

IMHO it is. I already wrote a DXL script to export DOORS modules to a LaTeX file which can be compiled into a PDF. You will find it at the end of this answer. Feel free to adapt it to your needs. Before you can run it you need to download the source of "Smart Folder Browser" and store it besides my script as "smartFolderBrowser.inc". Die extension inc indicates that this is an include file and not a standalone DXl program.

Of course every user which wants to use such an approach needs an installed TeX distribution like MiKTeX. The DXL script could start the PDF build after the export with the DXL built-in function void system(string command).

With your custom DXL LaTeX export script you will have to full control over the layout of the resulting PDF. But be aware of the layout rules which TeX applies. It can be a very challenging task to configure (force) TeX to render a document as it has been created with M$ Word.
