示例

以下示例说明了fn：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>

上面的代码将产生以下结果-


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.
