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.
