I'm working with some IDML files generated by Adobe InDesign which are, in short, XML representations of INDD files, InDesigns main file format.
I want to link/embed one or more IDML files into another single IDML "master" file.
I managed to link multiple INDD files into the master file in InDesign itself, but can not figure out how to link IDML files. I also found that it is possible to link INDD files into IDML files, just not IDML into IDML.
I need to be working with IDML as opposed to INDD because I have to be able to manipulate the files in an easy way.
Is there any way to link IDML files into other IDML files? Or is there a possibility to convert my IDML files to INDD files with the help of PHP without having to use a real instance of InDesign?
edit to claryfy why I need this done:
My IDML master file is sort of a template for a site layout. The IDML files I need to embed represent single content boxes with specific layouts. To retain those layouts I deemed it best to just embed them into another document which is no problem with INDD but just with IDML.
