在AJAX 中，服务器端如果返回的XML 文档，则可以通过异步对象的responseXML 属性来获取器XML 数据。而开发者可以利用DOM 的相关方法对其进行处理。
假设服务器返回的XML 文档，如下所示：
| <?xml version="1.0" encoding="gb2312"?> |
| <list> |
| <caption>Member List</caption> |

客户端获得服务器端的该XML 数据，并将其显示在表格中。代码如下：
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> |
| <html> |
| <head> |
| <title>responseXML</title> |
| <style> |
| <!-- |
| .datalist{ |
| border:1px solid #744011; /* 表格边框 */ |
| font-family:Arial; |
| border-collapse:collapse; /* 边框重叠 */ |
| background-color:#ffd2aa; /* 表格背景色 */ |
| font-size:14px; |
| } |
| .datalist th{ |
| border:1px solid #744011; /* 行名称边框 */ |
| background-color:#a16128; /* 行名称背景色 */ |
| color:#FFFFFF; /* 行名称颜色 */ |
| font-weight:bold; |
| padding-top:4px; padding-bottom:4px; |
| padding-left:12px; padding-right:12px; |
| text-align:center; |
| } |
| .datalist td{ |
| border:1px solid #744011; /* 单元格边框 */ |
| text-align:left; |
| padding-top:4px; padding-bottom:4px; |
| padding-left:10px; padding-right:10px; |
| } |
| .datalist tr:hover, .datalist tr.altrow{ |
| background-color:#dca06b; /* 动态变色 */ |
| } |
| input{ /* 按钮的样式 */ |
| border:1px solid #744011; |
| color:#744011; |
| } |
| --> |
| </style> |
| <script language="javascript"> |
| var xmlHttp; |
| function createXMLHttpRequest(){ |
| if(window.ActiveXObject) |
| xmlHttp = new ActiveXObject("Microsoft.XMLHttp"); |
| else if(window.XMLHttpRequest) |
| xmlHttp = new XMLHttpRequest(); |
| } |
| function getXML(addressXML){ |
| var url = addressXML + "?timestamp=" + new Date(); |
| createXMLHttpRequest(); |
| xmlHttp.onreadystatechange = handleStateChange; |
| xmlHttp.open("GET",url); |
| xmlHttp.send(null); |
| } |
| function addTableRow(sName, sClass, sBirth, sConstell, sMobile){ |
| //表格添加一行的相关操作，可参看7.2.1节 |
| var oTable = document.getElementById("member"); |
| var oTr = oTable.insertRow(oTable.rows.length); |
| var aText = new Array(); |
| aText[0] = document.createTextNode(sName); |
| aText[1] = document.createTextNode(sClass); |
| aText[2] = document.createTextNode(sBirth); |
| aText[3] = document.createTextNode(sConstell); |
| aText[4] = document.createTextNode(sMobile); |
| for(var i=0;i<aText.length;i++){ |
| var oTd = oTr.insertCell(i); |
| oTd.appendChild(aText[i]); |
| } |
| } |
| function DrawTable(myXML){ |
| //用DOM方法操作XML文档 |
| var oMembers = myXML.getElementsByTagName("member"); |
| var oMember = "", sName = "", sClass = "", sBirth = "", sConstell = "", sMobile = ""; |
| for(var i=0;i<oMembers.length;i++){ |
| oMember = oMembers[i]; |
| sName = oMember.getElementsByTagName("name")[0].firstChild.nodeValue; |
| sClass = oMember.getElementsByTagName("class")[0].firstChild.nodeValue; |
| sBirth = oMember.getElementsByTagName("birth")[0].firstChild.nodeValue; |
| sConstell = oMember.getElementsByTagName("constell")[0].firstChild.nodeValue; |
| sMobile = oMember.getElementsByTagName("mobile")[0].firstChild.nodeValue; |
| //添加一行 |
| addTableRow(sName, sClass, sBirth, sConstell, sMobile); |
| } |
| } |
| function handleStateChange(){ |
| if(xmlHttp.readyState == 4 && xmlHttp.status == 200) |
| DrawTable(xmlHttp.responseXML); //responseXML获取到XML文档 |
| } |
| </script> |
| </head> |
| <body> |
| <input type="button" value="获取XML" onclick="getXML('9-4.xml');"><br><br> |
| <table class="datalist" summary="list of members in EE Studay" id="member"> |
| <tr> |
| <th scope="col">Name</th> |
| <th scope="col">Class</th> |
| <th scope="col">Birthday</th> |
| <th scope="col">Constellation</th> |
| <th scope="col">Mobile</th> |
| </tr> |
| </table> |
| </body> |
| </html> |
我们可以看到，在客户端获得XML 文件的代码如下：
<input type="button" value="获取XML" onclick="getXML('9-4.xml');">
也就是说，是直接取得XML 数据的。而实际开发中返回XML 数据的工作是通过服务器端（如：ASP.NET、JSP等）的代码动态生成的。换句话说，getXML('...') 中的文件地址应该是.aspx 或.jsp等动态页面的后缀。
使用jQuery 框架实现
如果在客户端使用jQuery 框架，实现AJAX 获得服务器端的XML数据。
代码如下：
| <html> |
| <head> |
| <title> demo </title> |
| <meta name="Author" content="xugang" /> |
| <script language="javascript" src="jquery.min.js"></script> |
| <script type="text/javascript"> |
| function getXML(addressXML){ |
| //使用jquery的ajax方法 |
| $.ajax({ |
| type:"GET", |
| url:addressXML, |
| dataType:"xml", //返回类型(区分大小写) |
| success:function(myXML){ |
| //each 遍历每个<member>标记 |
| $(myXML).find("member").each( |
| function(){ |
| var oMember="",sName="",sClass="",sBirth="",sConstell="",sMobile=""; |
| sName = $(this).find("name").text(); |
| sClass = $(this).find("class").text(); |
| sBirth = $(this).find("birth").text(); |
| sConstell = $(this).find("constell").text(); |
| sMobile = $(this).find("mobile").text(); |
| //添加行 |
| $("#member").append($("<tr><td>"+sName |
| +"</td><td>" + sClass |
| +"</td><td>" + sBirth |
| +"</td><td>" + sConstell |
| +"</td><td>" + sMobile +"</td></tr>")); |
| } |
| ) |
| } |
| }) |
| } |
| </script> |
| </head> |
| <body> |
| <input type="button" value="获取XML" onclick="getXML('9-4.xml');"> |
| <br/> |
| <TABLE class="datalist" id="member"> |
| <TR> |
| <TH scope="col">Name</TH> |
| <TH scope="col">Class</TH> |
| <TH scope="col">Birthday</TH> |
| <TH scope="col">Constellation</TH> |
| <TH scope="col">Mobile</TH> |
| </TR> |
| </TABLE> |
| </body> |
| </html> |
服务器端传递XML 数据的方式不变。
