Hi Paul , I came across the same situation and I am trying to follow Jesús Prieto indications but Trados Studio crashes immediately after I add the DTD file. It seems DTD definition file is supported, since it is included in the supported file types, as you can see from the screenshots below:

I tried to select ST4.dtd and it seems to take it, but then it crashes.

Where am I wrong?

Thanks a lot,

Alessia

I don't know why it's crashing, but frankly the DTD is very unlikely to help you anyway and this is why it's not there in the XPath rules because it probably doesn't contain any information to help with your parser rules anyway.  DTD has been mostly superseded by XSD because of its limitations.

I'd recommend you find another way to create your XML filetype.  DTD won't get you parser rules, doesn't support namespaces, and has various other limitations.  So anything you got from it you could probably add manually anyway.

If you have the sdlftsettings from your old version then use those instead to create a new filetype.

Hi Paul, thanks for your reply. We were able to use an old SDLftsettings file indeed.
