[OpenLayers-Users] show only specific objects, wms

[T at f!t]

Thank you for your answer.

I tried it, but it always show the default style. My code is like this.

theSLD_BODY= '<?xml version="1.0"
encoding="ISO-8859-1"?><StyledLayerDescriptor version="1.0.0"
xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd"
xmlns="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><NamedLayer><Name>Linien</Name><UserStyle><Title>Linienobjekte

linien = new OpenLayers.Layer.WMS("Linien",url,params,options);

linien.mergeNewParams({"SLD_BODY":theSLD_BODY});

I tried also

linien.mergeNewParams({ SLD_BODY : theSLD_BODY });

After this the Layer is draw again. But it has still the same style.
Do you know what the problem could be?
