[OpenLayers-Users] RE : general question

[James Leveille]

I've done something to allow a user to add a WMS on the fly.
 
Here's a few clues :
- I ask the user for the URL
- http request to get the capabilities
- from the answer to the getCapabilities, a pick up the title and the available layer(s) - something like :
 
       var xmlFormat = new OpenLayers.Format.XML();
       var xml = xmlFormat.read(oHttpRequest.responseText);
       var capFormat = new OpenLayers.Format.WMSCapabilities_1_1_1();
       var cap = capFormat.read(xml);
 
       // title
       myTitle=cap.service.title;
 
       // layers
       for (var i=0; i<cap.capability.layers.length;i++)
       {
           ...
       }

- the user selects the layer(s) of interest (I use the ItemSelector to do so)
- selected layer(s) is(are) added to the map (title previously extracted is used)
 
biggest problem I had :
- reading the XML returned for the getCapabilities with IE6 
 
hope it helps

Hello,

Is it possible with openlayers, that a user can add a WMS on the fly? Can OpenLayers be extended to act more like a geoportal? Or is it only meant for visualisation of preconfigurated wms?

Thanks!
