Ard Schrijvers,Markus Vaterlaus and Geert Josten,,,Many Thanks for your suggestions,,,
 
I tried the following way and it works,,
 
<map:match pattern="one">
     <map:generate src=""/>
     <map:serialize type="xml"/>
   </map:match>
   <map:match pattern="two">
     <map:generate src=""/>
     <map:serialize type="xml"/>
   </map:match>
 </map:pipeline>
 <map:pipeline>
   <map:match pattern="authorsbook.html">
     <map:aggregate element="cd">
       <map:part src="" element="author"/>
       <map:part src="" element="book"/>
    ;  </map:aggregate>
     <map:transform src=""/>
     <map:serialize type="html"/>
   </map:match>
