3631	Transformation from XML to MapFile only handles one PROCESSING element	Iregart	aboudreault	"Hello Mapserver team,

I encountered a bug, transforming a mapfile XML to the mapfile format.
It seems, that only one PROCESSING element is written into the resulting mapfile, even if there are more defined in the XML.

Here is what I did:[[BR]]
- I used only the contents of the folder ''xmlmapfile'', contained in the 5.6.5 source release.[[BR]]
- I used the mapfile.xsd to create a source binding (JAVA) in a Eclipse plug-in.[[BR]]
- The binding classes I used to create the contents of the mapfile XML in memory.[[BR]]
- Then I transformed the mapfile XML into the original mapfile format, using the mapfile.xsl.[[BR]]
- The written mapfile only contains one PROCESSING directive, even if I add two elements into the XML.[[BR]]

This is, how I fill the processing element of a layer:
{{{
    double min = 0.0;
    double max = grid.getMax();
    double buckets = Math.floor( max / 0.05 );

    List<String> processing = layer.getProcessing();
    processing.add( String.format( Locale.PRC, ""SCALE=%.2f %.2f"", min, max) );
    processing.add( String.format( Locale.PRC, ""SCALE_BUCKETS=%d"", (int) buckets ) );
}}}

This is the result of the transformation:
