JSP Documents-java ee5 tutorial

 使用JSP Documents创建XML数据：

<books
    xmlns:jsp="http://java.sun.com/JSP/Page"
    xmlns:c="http://java.sun.com/jsp/jstl/core"
>
  <jsp:useBean id="bookDB" class="com.sun.books.database.BookDB" scope="page" >
    <jsp:setProperty name="bookDB" property="database" value="${bookDBAO}" />
  </jsp:useBean>

  <c:forEach var="book" begin="0" items="${bookDB.books}">
    <book id="${book.bookId}" >
        <surname>${book.surname}</surname>
        <firstname>${book.firstName}</firstname>
       <title>${book.title}</title>
    <price>${book.price}</price>
    <year>${book.calendar_year}</year>
    <description>${book.description}</description>
    <inventory>${book.inventory}</inventory>
    </book>
  </c:forEach>
</books>

注意配置JSPX：

<jsp-config>
    <jsp-property-group>
      <display-name>books</display-name>
      <url-pattern>*.jspx</url-pattern>
      <el-ignored>false</el-ignored>
      <scripting-invalid>false</scripting-invalid>
      <is-xml>true</is-xml>
    </jsp-property-group>
  </jsp-config>

指定数据：

<c:if test="${empty applicationScope.booklist}" > 
  <c:import url="${initParam.booksURL}" var="xml" />
  <x:parse doc="${xml}" var="booklist" scope="application" />
</c:if>

使用数据：

<%@ include file="/books/parsebooks.jsp" %>
<p><b><fmt:message key="What"/></b></p>
<x:set var="book" select="$applicationScope:booklist/books/book[@id='203']" />
<p/>
<c:url var="url" value="/books/bookdetails" />
