用jsp将xml文件解析到网页显示，并把数据提交保存到数据库

核心提示：Document document=questionDB.parse(pageContext.getServletContext().getResourceAsStream ("question.xml"));Element element = document.getDocumentElement

Document document=questionDB.parse(pageContext.getServletContext().getResourceAsStream ("question.xml"));
Element element = document.getDocumentElement();
NodeList questions = element.getElementsByTagName("question");

<form name="questionform" id="questionform" action="questionsave.jsp" method="POST">
