jQ处理xml文件和xml字符串的方法(详解)-PHP开发

<?xml version="1.0" encoding="utf-8" ?><root>  <book id="1">    <name>锋利的jQuery1</name>    <author>XXX1</author>    <price>250</price>  </book>  <book id="2">    <name>锋利的jQuery2</name>    <author>XXX2</author>    <price>99</price>  </book>  <book id="3">    <name>锋利的jQuery3</name>    <author>XXX3</author>    <price>108</price>  </book>  <book id="4">    <name>锋利的jQuery4</name>    <author>XXX4</author>    <price>128</price>  </book></root>

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        }      })    }

3.jQuery处理xml字符串

//jQuery解析xml字符串      var xmlStr = "<root><book id='1'><name>锋利的jQuery1</name><author>XXX1</author><price>250</price></book><book id='2'><name>锋利的jQuery2</name><author>XXX2</author><price>99</price></book><book id='3'><name>锋利的jQuery3</name><author>XXX3</author><price>108</price></book><book id='4'><name>锋利的jQuery4</name><author>XXX4</author><price>128</price></book></root>";      var $xmlDoc = $($.parseXML(xmlStr));      var $books = $xmlDoc.find("book");      var $names = $xmlDoc.find("name");      alert($($names[0]).text());      //其他操作与2相同
