Could you help one more time, pls...
Imagine the following XML snippet
<rdf:RDF>
<rdf:Description>
<FileName>image.jpg</FileName>
<Description></Description>
<GPS:GPSLatitude></GPS:GPSLatitude>
<GPS:GPSLongitude></GPS:GPSLongitude>
<GPS:GPSAltitude></GPS:GPSAltitude>
</rdf:Description>
</rdf:RDF>
If I use this with the command: exiftool -q -overwrite_original -all= -author 'Yarda' -tagsfromfile %f.xml I will end up with empty DESCRIPTION which is not nice but bearable; however, my GPS will be set to 0,0,0
GPS Position : 0 deg 0' 0.00", 0 deg 0' 0.00"
which is bad...
How to use/filter only what has some meaningful content? I tried to us -if but that is for a different usage. Some filter? -api
Thank you for comments.
Yarda.
Hi Yarda,
This may affect other tags, but for the example you gave adding -n to the command will prevent ExifTool from trying to convert the Lat/Long values to something meaningful. However, then the GPS coordinates must be in degrees only if they exist.

In my case I have this format, so that the -n is not what I can use...
<GPS:GPSLatitude>22.0355822000000003413333616 N</GPS:GPSLatitude>
<GPS:GPSLongitude>11.1165017999999999886995283 E</GPS:GPSLongitude>
So, need to do some filtering of "unwanted/empty" tags outside of exiftool then...

Did I say that? I can think of at least three other ways to do this with ExifTool. I just tried the easiest one first, given the situation you presented.
Try adding this to your command instead:
-api 'filter=$_ = undef unless length'- Phil
No, you did not say that! I was wrongly reading in between your lines... :-D
The suggested filter of yours works like a charm.
Thank you.
