XSL to extract data from a msGMLOutput XML response
Raw
README.markdown

This XSL tries to force the response from a WMS server and get a complete XML instead of a styled HTML page.

Why this works

The URL is like

http://www.cartografiarl.regione.liguria.it/CartoWebNet/CwGetFeatureInfo.aspx?FILE=E:\\Progetti\\MapServer\\tmp\\2053ebdc-2f9f-4adc-99d8-7feae362e11e.gml&XslUrl=http://steko.ominiverdi.org/elettro.xsl

(and lots of other useless bloat parameters that I removed for my own sanity). The XSL can be changed as a parameter, and the server will accept any valid URL (so silly, you say).

Unfortunately, this doesn't seem to work. For some reason, Mapserver is apparently used to generate a GML file without any geospatial attributes.

Most standard templates to get an identity copy of the original XML fail.

Please note that the GML file path is really a temporary file, so after the session has expired it won't work. You need to pass through a WMSGetInfo request.

This is the URL to query the WMS server. It doesn't work, because it just gives a blank image. The reason is stated here: http://mapserver.org/ogc/wms_server.html#coordinate-systems-and-axis-orientation

not working:

http://www.cartografiarl.regione.liguria.it/MapServer/mapserv.exe?MAP=E:\Progetti\mapfiles\repertoriocartografico\INFRASTRUTTURE\1077GC.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=9,43.8,10,44.0&CRS=CRS:84&WIDTH=640&HEIGHT=480&LAYERS=L2726&STYLES=&FORMAT=image/png

working (notice the double BBOX=BBOX=): http://www.cartografiarl.regione.liguria.it/MapServer/mapserv.exe?MAP=E:\Progetti\mapfiles\repertoriocartografico\INFRASTRUTTURE\1077GC.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=BBOX=9,43.8,10,44.0&CRS=CRS:84&WIDTH=640&HEIGHT=480&LAYERS=L2726&STYLES=&FORMAT=image/png
