<info>Simple example</info>
</tag>
A simple test JSP, reverse.jsp:
<%@ taglib uri="/hello" prefix="examples" %>
<html>
<head>
<title>Reverse tag</title>
</head>
<body>
<i>
<examples:reverse>
Don't try to put HTML markup in here:
the results will be very interesting
Hello world
</examples:reverse>
<p />
<examples:reverse>
Able was I ere I saw Elba
</examples:reverse>
</i>
</body>
</html>
This should produce the following output:
The result of placing HTML markup in the tag body will be unpredictable; hence I've used the tag twice so
that I can introduce some formatting markup between the tag instances.
There are many useful applications for filtering body tags. One, which will be discussed in the next chapter, is
performing an XSLT transform on XML content.
