The subset tag is used to filter elements in the collection. It uses a filter to filter out unqualified elements, leaving a subset of the original set. For example:

1 <%@ Page Language="Java"ContentType="text/html; Charset=utf-8"%>2 <%@ taglib URI="/struts-tags"prefix="Struts"%>3 <%@ taglib URI="/struts-tags"prefix="s"%>4 <!DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en">5 <HTML>6 <Head>7 <title>My JSP ' index.jsp ' starting page</title>8 <Metahttp-equiv= "Pragma"content= "No-cache">9 <Metahttp-equiv= "Cache-control"content= "No-cache">Ten <Metahttp-equiv= "Expires"content= "0"> One <Metahttp-equiv= "keywords"content= "Keyword1,keyword2,keyword3"> A <Metahttp-equiv= "description"content= "This is my page"> - <!-- - <link rel= "stylesheet" type= "Text/css " href= "Styles.css" > the      - -  - <Struts:headTheme= "Ajax" /> -  + <styletype= "Text/css"> - BODY,TD{ + font-size:12px; A } at </style> - </Head> -  - <Body> -  -  in <H3><FontColor= "#0000FF"> &lt;Struts:append/&gt;Label</Font></H3> -  to <!--can be combined with subsetaction, through subset.action test effect - + <S:subsetSource= "Malelist"decider= "Decider">    <!--Filter Labels - -     <S:iterator>                                  <!--Traverse Filtered Results - the         <S:property/>                            <!--output values for each traversal - *         <BR> $     </S:iterator>Panax Notoginseng </S:subset> -  the </Body> + </HTML>

Malelist is the collection property in action, and decider is the Filter property in action. The decider must implement the Subsetiteratorfilter interface and the decide () method.
