Hello to everyone, I wonder whether it is possible to add comments to an existing property tree object. To be more specific: I read in some XML files and change some attribute values (both relaized using property tree). In addition to that I would like to add some comments to a specific path in the property tree. Looking inside the code of property tree I found a function 'write_xml_comment', but I'm not sure whether and how this function may be used to address my problem. With kind regards, René.
