[OpenLayers-Users] Parse WMC Extension element for INFO_FORMAT

[Semantica]

Found the solution (suggestions for improvement are welcome):

function getInfoFormat(layer) {
  var infoFormat = "text/html";
  var format = new OpenLayers.Format.XML();                     
  var doc =
format.read(document.getElementById('hiddenFieldContainingWMC').value);        
  var layerNodes = format.getElementsByTagNameNS(doc, '*', 'Layer');

  for (var i=0; i<format.getElementsByTagNameNS(doc, '*',
'Layer').length;i++) { 
                
    if(format.getChildValue(format.getElementsByTagNameNS(layerNodes[i],
'*', 'Name')[0]) == layer.params.LAYERS) {    
      var infoFormatNodes = format.getElementsByTagNameNS(layerNodes[i],
'*', 'InfoFormat');                    
      infoFormat = format.getChildValue(infoFormatNodes[0]); 
      }                
    }
            
    return infoFormat;        
}
