public class OutComponent
extends HTMLFragmentComponent

Component used to output a EL expression in the HTML body. Usage is equivalent of the JSTL core out element. The following attributes in the HTML element are used:

• value: contains the value to be evaluated. It may contain EL expression inside the ${ ... } area.
• escapeXml: indicates if the evaluated value should be escaped. This attribute is optional and default is true
• default: the value to be used if the value evaluates to null or an empty string. If not specified, the default is an empty string.

The attributes will have any HTML entity in their value decoded.

Examples:

Layout File Code	Output (HTML source code)
<el:out value="${1+1}&quot;">Example HTML</el:out>	2&quot;
<el:out value="${1+1}&quot;" escapeXml="false">Example HTML</el:out>	2"
<el:out value="${null}" default="&quot;">Example HTML</el:out>	&quot;
<el:out value="${null}" escapeXml="false" default="&quot;">Example HTML</el:out>	"
