Are you asking, "Can something like this be done in JSTL?" The answer is
yes:
<c:forEach items="${myPhones}" var="col" varStatus="s">
<c:if test="${s.first}">My phones are<ul></c:if>
<li><c:out value="${col}"/></li>
<c:if test="${s.last}"></ul>.</p></c:if>
</c:forEach>
This is useful because opening and closing <ul> tags won't print unless
the collection has at least one item. This avoids empty <ul></ul>
elements (which normally display fine but are technically an error).
