How to format string in JSTL core tags?

Question

I am using JSP EL. I have a string like "Village Green,Colgate University,Hamilton,NY". I want to show only Village Green. How can I do this?

<c:forEach items="${listOfSources}" var = "source">
    <option value="${source }" >${source }</option>
</c:forEach>

The option value should be the whole string, but I want to show only Village Green to select. How can I achieve this?

Use just substringBefore from JSTL assuming that you need String from0 to first ,

Code Snippet:

<c:out value="${fn:substringBefore(source,',')}"/>
