Hello,
I always have a same problem: how trasform a gml file to svg.I have a gml file
validated with xmlspy, and i want tranform it in svg format to visualise the
map (using xmlspy), this map should contain two lines when one represent the
road and the other represent the river.
but the result is a html file not a svg file, from this can you look my
following files, to help me found the error:
