Example 1

The following expression contains a simple break terminating a loop.

<dolist name=’el’>
<ref>list</ref>
   <cond><eq><ref>el</ref><s>000</s></eq>
      <break>
         <ref>el</ref>
      </break>
   </cond>
<null/>
</dolist>

In this example, the dolist function iterates over the elements of a list looking for value 000. The value of the dolist function is a list formed by concatenating the values that are returned by the last subexpression in each iteration.
