# JSTL fn:escapeXml() Function

The fn:escapeXml() function escapes characters that can be interpreted as XML markup.

## Syntax:

The fn:escapeXml() function has following syntax:

    java.lang.String escapeXml(java.lang.String)

## Example:

Following is the example to explain the functionality of this function:

    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/functions"
                                                      prefix="fn" %>
    <html>
    <head>
    <title>Using JSTL Functions</title>
    </head>
    <body>

    <c:set var="string1" value="This is first String."/>
    <c:set var="string2" value="This <abc>is second String.</abc>"/>

    <p>With escapeXml() Function:</p>
    <p>string (1) : ${fn:escapeXml(string1)}</p>
    <p>string (2) : ${fn:escapeXml(string2)}</p>

    <p>Without escapeXml() Function:</p>
    <p>string (1) : ${string1}</p>
    <p>string (2) : ${string2}</p>

    </body>
    </html>

This would produce following result:

    With escapeXml() Function:
    string (1) : This is first String.
    string (2) : This <abc>is second String.</abc>

    Without escapeXml() Function:
    string (1) : This is first String.
    string (2) : This is second String.
