JSTL - fn:escapeXml() 函数

fn:escapeXml() 函数转义可解释为 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

以下示例说明了 fn:escapeXml() 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>

您将收到以下结果 -

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.
