In general, it should not be possible to import anything else than text. So adding HTML to GPX should not work.
For security reasons we do special handling on user imported files to make sure you can’t inject 3rd party code. See: Cross-site scripting - Wikipedia
That said, the GPX schema defines a linkType that we could probably support (and that you already tried to use). I tested this locally and this works, I will need to do a few more checks to make sure we are actually not introducing a security issue.
I did not want to create additional effort, I think the prio is low (especially compared to the topics concerning the new app).
But I am not sure if I fully understand how to embed a link in GPX - I just entered a link in the waypoint edit mask in Mapsource (very old fashioned, I know ), exported the waypoint to GPX and tried to get it in Kurviger.
I think in general it is a good idea to avoid embedding HTML - I “crashed” the layout of an alpenrouten.de comment unintendedly by entering a Google Maps link in my comment Col de la Bigue - Alpen-Motorrad-Guide
@moderators : I put copyright remarks and links to dangerousroads.org in the GPX - if you think that nevertheless it is not allowed to provide that GPX here, please give feedback or remove it immediately.
In that case I can think about providing a converter - then everyone has to extrakt the KMZ from dangerousroads.org himself and put it in the converter.
Perhaps I should provide that GPX in an an other thread (in “Nice routes - reports and recommendations”) - if yes, please give feedback, then I will create it.
Perhaps in the future it might be a benefit for Kurviger to embed points from dangerousroads.org as Kurviger POIs … there are also a lot of interesting POIs wordwide, I put them all in one GPX (more than 7000 POIs), but that breaks down performance of Kurviger in browser, I am thinking about breaking that down into regions …
@rumbrummer
Ich finde diese Datei super. Mittlerweile sind das auf der Webseite wohl schon ca. 13.000 POI’s.
Hast Du das ev. nochmal mit den aktuellen dangerousroads POI’s gemacht, bzw. kannst Du das (mich interessiert Eropa) nochmal aktuell machen und hier verlinken?
Ich habe leider keine Ahnung wie man solche Daten von der Webseite extrahiert.
