I am new to XSLT and working on transformation from one XML to another and facing below issue

If Book 1 node exist then I should not see Book 2 node into transformed XML. I tried different phrases but doesn't work.

Input XML

<Catalog>
   <Book 1></Book 1>
   <Book 2></Book 2>   

Expected XML

<Catalog>
   <Book 1></Book 1>      
</Catalog>
