Thanks for the reply Psychoadept. I am not a technical person (parsing, coding, etc), but the post you sent me had an option that I could use to start making progress. File>Library>Import>Import from Itunes in its current state took care of the following:
Rating and Track moved over as expected.
Not only did Count move, but the Date Last Played was updated as well which is one of the what of the new fields requested. Suggest that "Date Last Played" be added to the top text line of the dialog/instruction dialog box (containing Track, rating and Count), to set total expectations.
My requested Date Modified was untouched by the updating of the MBL file, so effectively the Itunes modified date was untouched which is the desired result.
The only remaining non-fulfilled wish is that the original iTunes Added Date can overwrite the values in the corresponding MBL/Track file(s). If there is a separate Date Added field in the MBL file that is used for listing purposes, this might be possible programatically. If the Music Bee Date Added field is the one in the Music/Track file, this might not be possible, as this may be a system function that cannot be over-ridden (as well as maybe treating this as a Modification and changing that corresponding Modified Date as well). Hopefully this is clear. Any possibility on this remaining field/behavior? Again, I know my limitations, so scripting/parsing etc. is not in my toolbag
Thanks for your help! Making progress....
fyi -- I had difficulty getting the Import function to work until I named a copy of the xml file I was using to "Itunes Music Library.xml". Any other file name would not work and should be stated, or have the program show *all* xml files in the directory and allow any named xml file to be selected/used .....
