2.jQuery代码

 window.onload = function () {
            //get解析xml文件
            $.get("1.xml", function (data) {
                $data = $(data);
                //获得节点
                var $books = $data.find("book");
                var $names = $data.find("name");
                var $authors = $data.find("author");
                //var $authors = $data.find("author") = $books.children("author") = $names.siblings("author");//获得books的子节点
                //获得属性、节点text
                //var id = $($books[0]).attr("id") = $books[0].getAttribute("id");//获得第一个book的id属性
                $authors.each(function () {
                    var author_text = $(this).text(); //获得节点内部文本,尝试过用nodeValue无果(不兼容)
                })
            })
            //ajax解析xml文件
            $.ajax({
                url: "1.xml",
                dataType: "xml",
                success: function (data) {
                    var $data = $(data);
                    var $books = $data.find("book");
                    //以下操作同上
                }
            })
