fn:escapeXml()函数


fn:escapeXml()函数忽略用于XML标记的字符。

语法

fn:escapeXml()函数的语法如下:

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

实例演示

以下实例演示了这个函数的功能:

<%@ 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>

运行结果如下:

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.
