I am facing an issue, that I want to show multiple labels on each polygon of OpenLayers. I am defining styles in style editor of a layer.like 

 <sld:Label>
           ogc:PropertyName>XYZ< /ogc:PropertyName>             
 </sld:Label>

where xyz is one of the columns in my query. Now I want to show one more column on the polygon from query and the attribute should be one after the other on the polygon.

In general SLD (though I haven't tested it in OpenLayers) you can do:

<sld:Label>
       <ogc:PropertyName>XYZ</ogc:PropertyName>             
       <ogc:PropertyName>ABC</ogc:PropertyName>             
 </sld:Label>

and they will be concatenated. If you need more than one white space you can play around with a [CDATA] block to contain extra white space.

  • Yes. I was using the same way but the second property is comming null from database. Because of this region the entire label is not showing.

  • replace the nulls with empty strings

  • I need to check whether the property is null. If it is null then need to show NA else the value. How to achieve this in SLD?

  • No standard way - if you are using GeoServer check out the functions
