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.
