Hello people, this must simple for most.

Hello people, this must simple for most. How do I handle in a simple form a TXMLData? I have access to consume a webserver, so I have a method that returns a table. I need to read data attributes but I am missing something, I've done like:

with (HTTPRIO1 as ServiceSoap) do 
begin 
    xdata := TXMLData.Create;   
    xdata := readTheTable(params); 
  .  
  . 
  . 
   xdata.Free; 
end; 
  
I can just get the xsd structure info, not the data itself.
