generateSLD bug

[Yewondwossen Assefa]

Hi There,

  The expression parsor will work if some rules are followed like 
appropriate brackets and spaces between operator and values. In your 
case here are the expressions that should give you a valid output:

   1)  EXPRESSION ([fieldname] > 20 AND [fieldname] <= 40)
     result : <ogc:Filter><AND> 
<ogc:PropertyIsGreaterThan><ogc:PropertyName>fieldname</ogc:PropertyName><ogc:Literal>20</ogc:Literal></ogc:PropertyIsGreaterThan> 
<ogc:PropertyIsLessThanOrEqualTo><ogc:PropertyName>fieldname</ogc:PropertyName><ogc:Literal>40</ogc:Literal></ogc:PropertyIsLessThanOrEqualTo></AND></ogc:Filter>



   2)  EXPRESSION ([fieldname] <= 40)
      result : <ogc:Filter> 
<ogc:PropertyIsLessThanOrEqualTo><ogc:PropertyName>fieldname</ogc:PropertyName><ogc:Literal>40</ogc:Literal></ogc:PropertyIsLessThanOrEqualTo></ogc:Filter>


  Let me know if it works.
