Re: [josm-dev] MapCSS: Substitute characters in a text
Recently support for regular expressions was added to the JOSM implementation of MapCSS. http://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation#Evalexpressions Maybe you can accomplish what you need with regexp_match(regexp, string, flags) It will return a list of matching groups, but I'm not sure how you can get back from a list to a string. It would be more convenient if the good soul who added the regex support would also add a regex replace function. Polyglot 2013/4/6 Martin Vonwald imagic@gmail.com Hi! Within a MapCSS style I have to replace some characters in an arbitrary text by others. Example: Roma - Napoli should be changed to Roma -#x3E; Napoli. The text comes from a tag so I don't have any knowledge of its content in advance, but I have to get rid of some characters. Any ideas how to do that? best regards, Martin ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev

Hi! I already tried that before asking on this list. But maybe I didn't use it correct, so I hoped that someone here could give me a hint.

Re: [josm-dev] MapCSS: Substitute characters in a text
Hi,
this should work:
*[name=~/-/]{
_match: regexp_match((.*?)-(.*), tag(name));
text: concat(get(prop(_match), 1), -#x3E;, get(prop(_match), 2));
}

Re: [josm-dev] MapCSS: Substitute characters in a text
Hi! Thanks, but you missed that part: The text comes from a tag so I don't have any knowledge of its content in advance, but I have to get rid of some characters. The Roma - Napoli was just an example. I don't know how many characters I have to replace. I just need to get rid of all , , [ and ] (at least, maybe more), otherwise JOSM gets really angry with me ;-) Thanks!
