[OpenLayers-Users] WFSDescribeFeatureType - how to use it???

[Gabriel Nolasco]

Poul, try this:

var describeFeatureTypeRequest = OpenLayers.Request.GET({
    url: 'http://localhost:8080/geoserver2_0_1/wfs?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=topp:bazadanych'
    callback: parseFeatureTypes
});

var parseFeatureTypes = function(response) {
    var featureTypesParser = new OpenLayers.Format.WFSDescribeFeatureType();
    var responseText = featureTypesParser.read(response.responseText);
    var featureTypes = responseText.featureTypes;
    
    for(var i=0; i<featureTypes[0].properties.length; ++i) {                        
        alert('attribute is named ' + featureTypes[0].properties[i].name);
        alert('attribute is of type ' + featureTypes[0].properties[i].type);
    }
};

Best regards,

Gabriel Nolasco

Hi!

I was jus wandering if anyone please tell me how to use
WFSDescribeFeatureType class. I am thinking about getting the name of the
attributes from my database. I found a lot of examples like this:

    var text = 
            ' .........

            '      <extension base="gml:AbstractFeatureType">' +
            '        <sequence>' +
            '          <element name="geometry"
type="gml:MultiLineStringPropertyType" minOccurs="0" maxOccurs="1"/>' +
            '          <element name="SHAPE" type="string"/>' +
            '          <element name="SE_ANNO_CAD_DATA" type="string"/>' +
            '

    var parser = new OpenLayers.Format.WFSDescribeFeatureType();
    var res = parser.read(text);

Ok, this works just great, if describefeature is written in string... 
I want to get the name of my attributes from DescribeFeatureType via URL.
This is my url:

http://localhost:8080/geoserver2_0_1/wfs/DescribeFeatureType?version=1.1.0&typename=topp:bazadanych

If I do something like this:
var res =
parser.read("http://localhost:8080/geoserver2_0_1/wfs/DescribeFeatureType?version=1.1.0&typename=topp:bazadanych");
of course it will not work....
What is the way to read XML via URL and add it to the WFSDescribeFeatureType
class?? 
Can anyone please help me??

Regards,
Poul
