Exporting a scrivener outline to an .mm mindmap, how is the data content converted

I am writing an xslt transformation of the scrivener fml format to an .mm formatted file to be used by freeplane.

This is because certain information is lost such as hyperlinks is lost when scriven exports to the .mm format (at least in the beta windows version)

My bottleneck right now is that the text of a document resides in the data folders in rtf format as (for example)

{\fonttbl{\f0\fmodern\fcharset0\fprq2 Calibri;}}
\pard\plain \tx0\tx360\tx720\tx1080\tx1440\tx1800\tx2160\tx2880\tx3600\tx4320\fi360\sl264\slmult1\ltrch\loch {\f0\fs26\b0\i0 Text contents of \loch\af0\hich\af0\dbch\af0\uc1\u8220’93new text1\u8221’94}}

, but shows up in the .mm file as

Text contents of “new text1”

Can you help me understand how to convert the rtf contents to the richcontent.,? Perhaps it should be obvious, but… not to me.
