JSTL - XML <x:out> Tag


The <x:out> tag displays the result of an XPath expression. It functions the same as <%= %> JSP syntax.


The <x:out> tag has the following attributes −

Attribute Description Required Default
select XPath expression to evaluate as a string, often using XPath variables Yes None
escapeXml True if the tag should escape special XML characters No true


Let us take an example which will cover the tags (a) <x:out>, (b) <x:parse>.

<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix = "x" uri = "http://java.sun.com/jsp/jstl/xml" %>

      <title>JSTL x:out Tags</title>

      <h3>Books Info:</h3>

      <c:set var = "xmltext">
               <name>Padam History</name>
               <name>Great Mistry</name>

      <x:parse xml = "${xmltext}" var = "output"/>
      <b>The title of the first book is</b>: 
      <x:out select = "$output/books/book[1]/name" />
      <b>The price of the second book</b>: 
      <x:out select = "$output/books/book[2]/price" />

The above code will produce the following result −

Books Info:

The title of the first book is: Padam History The price of the second book: 2000
