Thanks Deadfast, that worked for the line breaks. However my markers still aren't linked in the Briefing. E. g.:
<marker name='pl_viper'/>PL Viper</marker/>
for
<marker name='pl_viper'/>PL Viper</marker/>
Shows the text PL Viper in the briefing but not the link. Are there more characters I need to mask in order for that to work, the = and ' maybe?
Also I masked Umlaute (ü, ä, Ü, Ä ...) with ü ä etc. but they are displayed as question marks in the briefing. Is this caused by the UTF-8 encoding I use in the xml? Would it help to use another encoding (Unicode for example)?
