JOSM: Validation duplicate tag value

Hello everyone

I try to write a JOSM-Validation with mapcss. The validation should find all nodes in the downloaded area with the same value of a certain tag.
There seems to be a similar check for housnumbers, but as far as I understood this validation is not written in mapcss…
I couldn’t find a suitable function available according to JOSM’s MapCSS implementation

How could I possibly achive this?


Hmm, if you think that a certain tag is wrong look at the samples in deprecated.mapcss. You probably want to find two objects within a max. distance having a given tag? If yes there is currently no selector implemented in JOSM which would support that.

You could use the filter function which enables quite complex filtering of objects / certain tags.
