Ok. I see what you did there. :) I only just started using XSLT so I'm not actually any good at it, but I recognise the power of the tools, so I know it's worth persevering. >> For an area I will match "way" but then I have to get all nodes that >> make the way and calculate a simple centroid. > > Using an xsl:key is the way to go here: > <snip> Thanks for the code. I will try it out. The end result will be a simple textfile containing a certain type of amenity. I will load it up as a layer using this example: http://wiki.openstreetmap.org/wiki/Openlayers_POI_layer_example#textfile.txt It means I can make a local map with half a dozen layers for different amenities (restaurants, shops, schools, public buildings, etc.) to make a 'Town Guide'. It will be sort of interactive insofar as you can turn the layers on and off. Again, there are probably better solutions out there, but this is a concrete way to learn XSLT. I also like the idea of not having to write too much code. The workflow is: 1. download region from OSM 2. Run XSLT to make POI layers 3. Err, 4. That's it!
