Check Folder exist in sharepoint lists via GetListItems web service

Hi,

I'm able to find the folder availability in share point lists using below code snippet.

try           
  {                             
      Guid guid = new Guid(listGUID);                              
      SPSite site = new SPSite("http://localhost:8081/");               
      SPWeb website = site.OpenWeb();
      SPList listname = website.Lists[guid];
      //Check if the Folder is already available in the list
      SPQuery query = new SPQuery();               
      query.Query = "<Where><And><Eq><FieldRef Name='Title'/><Value Type='Text'>" + "assignmentfolder" + "</Value></Eq><Eq><FieldRef
                      Name='FSObjType'/><Value Type='Lookup'>1</Value></Eq></And></Where>";   
        query.ViewAttributes = "Scope=\"RecursiveAll\"";               
      //Retrieve the items based on Query               
      SPListItemCollection items = listname.GetItems(query);               
      //Item count is "0" if the folder does not exist
        if (items.Count == 0)                                  
              return false;         
  }
catch (Exception ex) {}          

As per the architecture of my project, I need to implement above said code using "GetListItems" web service.

              
XmlNode query = null;                
XmlNode qryOptions = null;                
string foldernme = "People";                
query = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "<Where><And><Eq><FieldRef Name='Title'/><Value Type='Text'>" + foldernme + "</Value></Eq><Eq><FieldRef Name='FSObjType'/><Value Type='Lookup'>1</Value></Eq></And></Where>");                
qryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "<ViewAttributes Scope='RecursiveAll'/>");
XmlNode getFolders = ListWebService.GetListItems(listGUID, null, query, null, null, qryOptions, null);

The web service returning all the folders which are resides in the lists (see below: this is outcome of getfolders.outerXML). Instead of all the folders, I just want to check whether folders are exist or not.
