Simplest example would consist of:

1. Getting user input.

2. Composing XML SOAP message similar to this

   
     
       
         string
       
     
   
   

3. POSTing message to webservice url using XHR

4. Parsing webservice's XML SOAP response similar to this

   
    
     
      
       
        ...............
       
      
     
    
   
   

5. Presenting results to user.

But it's a lot of hassle without external JavaScript libraries.
