如何在 JSP 中转义可能会被解释为 XML 标记的字符?
fn:escapeXml() 函数转义了可能会被解释为 XML 标记的字符。
语法
fn:escapeXml() 函数具有以下语法 -
java.lang.String escapeXml(java.lang.String)
示例
以下是解释 fn:escapeXml() 函数功能的示例 -
<%@ 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>你会收到以下结果 -
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.
