[mkgmap-dev] comparison of relation tag and way tag

Mon Mar 16 14:12:07 GMT 2015

Hi, I have the following lines in my relations file:

type=route & (route~'.*foot.*' | route~'.*hiking.*') & network~'.*[nr]wn.*'
& name~".*\(.*\)" { set name='${name|subst:"\(.*\)~>"}'}
type=route & (route~'.*foot.*' | route~'.*hiking.*') & network~'.*[nr]wn.*'
& name=* { apply_once { set hikingroute=yes; set rn='$(rn) & ${name}' |
'${name}'; } }

This is working, but if for example the way has two hiking relations with
names "Shropshire Way (Route 1)" and "Shropshire Way (Route 2)", the first
rule changes the names of both relations to "Shropshire Way", and the second
rule sets the rn tag of the way to "Shropshire Way & Shropshire Way". I
would like to check whether the rn tag on the way already contains the name
of the relation (or is equal to if contains can't be done), so that I end up
with rn as "Shropshire Way". Can anyone tell me how this can be achieved?

Thanks,
Mike
