Open XML (DITA) file in FM as it was in Arbortext
I got the xml files, which are used with Arbortext XML Editor 5.3 in DITA, it has all the DTDs and styles files. I want to use the same XML files in FM to work with either in structures or unstructured way, I'm novice to structured FM. When I open XML file in FM it ask to choose Structured Application, I have chosen DocBook, Xdocbook but not getting it what i want it displays as simple plain text without any style, formatting, and images.

I just want the same look and feel of Arbortext some changes here and there i can manage though. I need to know what exactly I need to change, attaching the screen shot of XML file and file which opens in FM.

What can I do to use existing XML in FM 2015 or 2017.
