<body>
<c:set var="string1" value="This is first String."/>
<c:set var="string2" value="This <abc>is second String.</abc>"/>
<p>Using escapeXml() function:</p>
<p>string (1) : ${fn:escapeXml(string1)}</p>
<p>string (2) : ${fn:escapeXml(string2)}</p>
<p>Without using escapeXml() function:</p>
<p>string (1) : ${string1}</p>

Using escapeXml() function:
string (1) : This is first String.
string (2) : This <abc>is second String.</abc>
Without using escapeXml() function:
string (1) : This is first String.
string (2) : This is second String.
