You didn't explain what didn't work exactly. Like do you get a response with 
zero features in it ?

This might be an issue with the coordinate order of  in lowerCorner and 
upperCorner query. I assume that the SRS of the layer is EPSG:4326 ? If so, 
you should likely put the values in latitude longitude order (they look like 
being longitude latitude in your below sample). And it would also be better to 
explictly specify the SRS by adding a srsName="urn:ogc:def:crs:EPSG::4326" 
attribute to the <gml:Envelope> element.
