We found out what was not working for us. I've prepared a patch that
solved the problem.
Could anyone confirm that there is a bug in the original version, please ?
Kind regards,
Alexandre

Hi users,
I'm having a hard time using the WMSGetFeatureInfo format.
Instead of explaining, below's snippet (1). Because I currently
can't have a response from my server since I have problems with HTTPS
and proxy, I load a xml (see attached) instead ( it's a msGMLOutput
XML from MapServer ).
I get an empty features array. Any clue what I'm doing wrong ?
(1) /*---------snippet---------*/
showResult: function(response){
var oFeatures;
var oFormat = new OpenLayers.Format.WMSGetFeatureInfo();
if(!response){
var xmlDoc=document.implementation.createDocument("","",null);
xmlDoc.async="false";
xmlDoc.load("response.xml");
oFeatures = oFormat.read_msGMLOutput(xmlDoc);
} else {
oFeatures = oFormat.read_msGMLOutput(response.responseXML ||
response.responseText);
}
