hmm. I use a custom WFSCapabilities parser but dont otherwise have an
issue. Have checked your getcaps call directly as a browser URL (or
looked at the return in the NET tab).
My code is like this: (It is within the context of an ExtJS form but you
should see the essentials okay. It loads a store with a list of WFS layers).
function wfsGetCapabilities(node) {
var url = node.data.sQURL;
if (url.indexOf('?') < 0) url += '?';
if ((url.indexOf('?') + 1) < url.length) url += '&';
if (url != '?') {
Ext.Ajax.request({
url: 'FileHandling/adminproxy.jsp',
success: addWfsLayers,
params: {
url: url + 'service=WFS&request=GetCapabilities'
}
});
}
}
function addWfsLayers(response) {
var wfsGetCapabilitiesParsed = parseWFS(response.responseXML);
var node = getSelNode();
var layerData = [];
var layerToSelect = '';
for (i=0; i<wfsGetCapabilitiesParsed.featureTypes.length; i++) {
var layer = wfsGetCapabilitiesParsed.featureTypes[i];
layerData[i] = [layer.prefix + ':' + layer.name,layer.title];
if (layer.name == node.data.sQFeatureType) layerToSelect =
layer.title;
}
Ext.getStore('AvailableSpatialLayers').loadData(layerData);
if (layerToSelect != '') {
var spatialListCombo = Ext.ComponentQuery.query('libraryPanel
libraryLayerDetailsPanel spatialListCombo')[0];
spatialListCombo.setValue(layerToSelect);
spatialListCombo.fireEvent('select',spatialListCombo,'');
}
}
function parseWFS(xmlDoc) {
var featureTypeList = {
featureTypes: []
};
for (i=0; i<xmlDoc.documentElement.childElementCount; i++) {
var elem = xmlDoc.documentElement.childNodes[i];
if (elem.localName=='FeatureTypeList') {
for (k=0; k<elem.childElementCount; k++) {
var childElem = elem.childNodes[k];
if (childElem.localName=='FeatureType') {
var featureType = {};
for (j=0; j<childElem.childElementCount; j++) {
var field = childElem.childNodes[j];
var name = field.localName;
var text = field.textContent;
if (name=='Name') {
var parts = text.split(':');
featureType.name = parts.pop();
featureType.prefix = parts.pop();
} else if (name=='Title') featureType.title = text;
else if (name=='DefaultSRS') featureType.srs =
text;
}
featureTypeList.featureTypes.push(featureType);
}
}
}
}
return featureTypeList;
}
