I missed the import with xslt (like export with xslt)
So I "copied" the ImportMindManager... and the result is a import with xslt that can be configured to use any xslt.
(seems to work currently)
I've attached the file. And am very sorry for the worse java copying... ;)
Hopefully someone can 'clean it up'.
The ImportXML.xml and the xml2mm.xsl are examples.
so e.g. for the xbel2mm.xsl (which is in there) we only need a ImportXBEL.xml and ready to import ;)
