WMS question

[rock well]

Hi Bart, i am trying to use sld_body to specifiy the path of the localurl for the xml file, but i get a blank image, i didnt really get the concept of how to write an xml file and then send it through the sld_body tag, can you suggest me with a real time example where a clear description is given as to how to specify the map file in the xml ...
   
  well i guess i might have understood something wrong, but can you/anyone suggest me ...
   
  i cut down my xml file to the following lines as i dont know what other lines mean 
   
  <StyledLayerDescriptor version="1.0.0">
  <NamedLayer>
  <Name>Layer Name</Name> 
  </NamedLayer>
  </StyledLayerDescriptor>
   
  Thanks for your time

  This can be accomplished using SLD. In a WMS GetMap request you can add 
an inline SLD using the SLD_BODY parameter, or use the SLD parameter to 
point to a URL pointing to the actual SLD XML document.

The Chameleon ExpressionBuilder widget has some code to do this or check 
out:

If a WMS layer is queryable, you can perform a WMS GetFeatureInfo 
request against it using an X and Y value in pixels, which can return a 
plain text, HTML or GML document.

Best regards,
Bart
