A quick gander at http://taginfo.openstreetmap.org.uk/keys/phone#values suggests: - s/[^0-9]//g - s/^0/44/ will actually cope with almost every value currently extant. The exceptions are a few without area code at all, and a few semicolon-delimited multiple values (which is frowned upon in any case). > The "four lines of regex" will need to be different for each country Oh, indeed, but that's the case for most tagging in OSM anyway. Fortunately OSM is a spatial database so it's easy to do region-specific transformations! I don't particularly care about this specific issue because I can't really envisage circumstances in which I would want to use phone numbers derived from OSM. What I'm trying to get across is the general point that non-consumers' attempts to "normalise" tags, thinking that data consumers will appreciate it, isn't necessarily as helpful as you'd think. cheers Richard -- View this message in context: http://gis.19327.n5.nabble.com/Phone-numbers-in-little-England-tp5774459p5774643.html Sent from the Great Britain mailing list archive at Nabble.com. _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
