[OpenLayers-Users] XML Parsing via OpenLayers?

[Bart van den Eijnden (OSGIS)]

Maybe you can try and create your own Format class, something like:

/**
 * @requires OpenLayers/Format/XML.js
 *
 */
OpenLayers.Format.MyFormat = OpenLayers.Class(
    OpenLayers.Format.XML, {
   
    initialize: function(options) {
        OpenLayers.Format.XML.prototype.initialize.apply(this, [options]);
        this.options = options;
    },

    read: function(data) {
        if(typeof data == "string") {
            data = OpenLayers.Format.XML.prototype.read.apply(this, [data]);
        }
        // do your stuff here, it's just an example
        var root = data.documentElement;
        var children = root.childNodes;
        for(var i = 0; i < children.length; ++i) {
            childNode = children[i];
            var nodeName = childNode.nodeName;
            if (nodeName == 'Toolbar') {
              this.parseToolbar(childNode);
            }
        }
        // return your array here
    },
   
    CLASS_NAME: "OpenLayers.Format.MyFormat"

});


And then:

         OpenLayers.loadURL(myURL, "", null, function(response) {
             var format = new OpenLayers.Format.MyFormat();
             var myArray = format.read(response.responseXML || 
response.responseText);
             console.log(myArray);
         });

Best regards,
Bart
