AW: [OpenLayers-Users] WMSCapabilities

[Morper-Busch, Lucia]

After trying and searching finally I discovered the error!
The capabilities-XML of my Geoserver was corrupted! The xml structure was interrupted by the following ServiceExceptionReport:
 
<ServiceExceptionReport version="1.1.1" > <ServiceException>javax.xml.transform.TransformerException: Translator error Translator error Error occurred trying to write out metadata for layer: Pk50095 Unable to acquire a reader for this coverage with format: WorldImage</ServiceException></ServiceExceptionReport>

The xml-tags weren't closed. And so the document could not be read and parsed.

But the Pk50095-layer is an example layer of Geoserver, not added by me. That is very strange. Anyway, I deleted the layer, and the request gave me the desired response.

Hello,
I want to read the WMS capability xml, in order to get the abstract and
the metadata link of each layer.

My code is:

var request = OpenLayers.Request.GET({
        url: url +
'?service=wms&version=1.1.1&format=text/xml&request=getcapabilities'
        ,success: function(response){
                //alert(response.responseText);
                var obj = new
OpenLayers.Format.WMSCapabilities.v1_1_1().read(response.responseText);
//var obj = new
OpenLayers.Format.WMSCapabilities().read(response.responseText);
                var capability = obj.capability;
                for (var i=0, len=capability.layers.length; i<len; i++)
{
                        var layerObj = capability.layers[i];
                        alert(layerObj.name);
                }
        }
})

The error is: "capability is undefined"

But "response.responseText" gives me the right xml as text.
"response.responseXML" is null.

response properties:

        _object: [object XMLHttpRequest]
        _listeners:
        _async: true
        readyState: 4
        responseXML: null
        statusText: OK
        status: 200
        priority: NORMAL

I use a proxy, that works fine for getFeatureInfo-Requests.

What is my problem?

Thank you
Lucia
