struts中iterate标签的一个例子（一层嵌套）

在action里servletRequest.setAttribute(“survey“,survey);

jsp文件片断（注意：不需usebean，标签会自动找）：

<nested:write name="survey" property="title"/><br>

<nested:write name="survey" property="poster"/><br>

<nested:write name="survey" property="postDate"/><br>

<nested:iterate id="item" name="survey" property="items" type="survey.SurveyItem">

<nested:equal name="item" property="type" value="select_single">

<nested:write property="title"/><br>

options:<br>

<nested:iterate id="option" name="item" property="options" type="survey.SurveyItemOption">

<nested:write property="index"/>

<nested:write property="text"/><br>

</nested:iterate>

</nested:equal>

<nested:equal name="item" property="type" value="select_multi">

<nested:write property="title"/><br>

options:<br>

<nested:iterate id="option" name="item" property="options" type="survey.SurveyItemOption">

<nested:write property="index"/>

<nested:write property="text"/><br>

</nested:iterate>

</nested:equal>

<nested:equal name="item" property="type" value="text">

<nested:write property="title"/><br>

</nested:equal>

</nested:iterate>
