Using Liferay Util Buffer
The buffer tag is not a self-closing tag. The content placed between the opening and closing of this tag is saved to a buffer and its output is assigned to the Java variable declared with the tag’s var attribute. The output is returned as a String, letting you post-process it. For example, you can use this to override a JSP’s existing contents.
The example below saves the link’s generated markup to a buffer and then uses the returned string as the argument for a liferay-ui:message key:
<liferay-util:buffer
var="linkContent"
>
<aui:a
href="https://www.liferay.com/"
target="_blank">Liferay
</aui:a>
</liferay-util:buffer>
<liferay-ui:message
arguments="<%= linkContent %>"
key="see-x-for-more-information"
translateArguments="<%= false %>"
/>
Now you know how to use the <liferay-util:buffer> tag to save content to a buffer.
