SLD Filters

[Yewondwossen Assefa]

Hi There,

  I have made a couple of tests using the tests data here (url is at
http://www2.dmsolutions.ca/cgi-bin/mswms_world?SERVICE=WMS&VeRsIoN=1.1.1&Request=GetMap&LAYERS=WorldGen&SLD=http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_polygon_one_filter_and_else2.xml)

  The sld has a same kind of structure as yours (polygon symbolizer with
one filter and one else filer) and seems to apply the filters properly.
If you can provide me with sample data and sld that does not work, I can
check it more specifically.

Later,
