    e1067.  
    Saving and Emitting HTML Fragments Using JSTL in a JSP Page</h3>

When saving text with the special characters <code>&lt;&gt;'"&amp;</code>, the special
characters are save as is; there is no translation that takes
place. However, when emitting text with <code>&lt;c:out&gt;</code>, these special
characters are translated to the equivalent XML entities.  In
particular, <code>&lt;</code> becomes <code>&amp;lt;</code>, <code>&gt;</code> becomes <code>&amp;gt;</code>, <code>'</code>
becomes <code>&amp;#039;</code>, <code>"</code> becomes <code>&amp;#034;</code>, and <code>&amp;</code> becomes
<code>&amp;amp;</code>. This means that a value such as <code>&lt;b&gt;</code> will be emitted
as <code>&amp;lt;b&amp;gt;</code> and therefore not be interpreted as the HTML <code>b</code>
tag.

<P> To prevent this translation, the <code>escapeXml</code> attribute
must be specified and set to <code>false</code>:


<pre>
    &lt;%-- Declare the core library --%&gt;
    &lt;%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %&gt;
    
    &lt;%-- Save data with html tags --%&gt;
    &lt;c:set var="msg" value="hi &lt;b&gt;John&lt;/b&gt;!" scope="page" /&gt;
    
    &lt;%-- Show the value after translating special characters --%&gt;
    &lt;c:out value='${msg}' /&gt;
    
    &lt;%-- Show the value without translating special characters --%&gt;
    &lt;c:out value='${msg}' escapeXml="false" /&gt;
</pre>
