[Users] Question using GeoExt with WFS servers

[Christopher Eykamp]

Hello!

This is probably a very simple question but I just can't seem to figure 
it out.

I am writing a Javascript app to retrieve layer information from a WFS 
server using a GetCapabilities request using GeoExt. GetCapabilities 
returns information about the WFS server -- the server's name, who runs 
it, etc., in addition to information on the data layers it has on offer.

My basic code looks like this:

=====
var store = new GeoExt.data.WFSCapabilitiesStore({ url: serverURL });

store.on('load', successFunction);
store.on('exception', failureFunction);
store.load();
=====

This works as expected, and when the loading completes, successFunction 
is called.

successFunction looks like this:

=====
successFunction = function(dataProxy, records, options) {
    doSomeStuff();
}
=====

dataProxy is a Ext.data.DataProxy object, records is a list of records, 
one for each layer on the WFS server, and options is empty.

And here is where I'm stuck: In this function, I can get access to all 
the layer information regarding data offered by the server. But I also 
want to extract the server information that is contained in the XML 
fetched during the store.load() (see below). I can't figure out how to 
get it out of the dataProxy object, where I'm sure it must be squirreled 
away.

Any ideas?

The fields I want are contained in this snippet:

=====
<ows:ServiceIdentification>

   <ows:Abstract/>
   <ows:Keywords>
      <ows:Keyword/>

   <ows:ServiceType>WFS</ows:ServiceType>
   <ows:ServiceTypeVersion>1.1.0</ows:ServiceTypeVersion>
   <ows:Fees/>
   <ows:AccessConstraints/>
=====

Thank you!
