[mapserver-users] Using applySLD and generateSLD with Mapscript Python

[Guillaume Sueur]

Hi list,

I'm playing with mapscript python and SLD files, and having some kinds 
of troubles.
It seems that applySLD doesn't build an EXPRESSION tag for the CLASS it 
refers too.
Starting from a mapfile with CLASS and EXPRESSION set, the SLD body 
generated is correct :
<Rule>
<Name>VELOV</Name>
<ogc:Filter><ogc:PropertyIsGreaterThanOrEqualTo><ogc:PropertyName>nbbornettes</ogc:PropertyName><ogc:Literal>20</ogc:Literal></ogc:PropertyIsGreaterThanOrEqualTo></ogc:Filter>
<PointSymbolizer>
<Graphic>
<Mark>
<WellKnownName>square</WellKnownName>
<Fill>
<CssParameter name="fill">#993300</CssParameter>
</Fill>
</Mark>
<Size>8</Size>
</Graphic>
</PointSymbolizer>
</Rule>

but applying this same SLD file to the mapfile via mapscript gives only 
a FILTER set:
FILTER  ("nbbornettes">= 20)
...
CLASS
       NAME "VELOV"
       STYLE
         ANGLE 0
         COLOR 153 51 0
         OFFSET 0 0
         SIZE 8
         SYMBOL "sld_mark_symbol_square_filled"
       END # STYLE
     END # CLASS

The matching between SLd Filters and Classes has been lost. It means 
that you can't build any SLD file with more than one class/filter and 
see them drawn on the map.
I 'm using mapscript 6.0.1

Thanks for any clue

Best regards

Guillaume
