其中a为append Child
1：
<?php
header("Content-type: text/xml");
echo "<?xml version="1.0" encoding="UTF-8"?>";
echo "<users>";
echo "<user>";
   echo "<name>";
    echo "小小菜鸟";
   echo "</name>";
   echo "<age>";
    echo "24";
   echo "</age>";
   echo "<sex>";
    echo "男";
   echo "</sex>";
echo "</user>";
echo "<user>";
   echo "<name>";
    echo "艳艳";
   echo "</name>";
   echo "<age>";
    echo "23";
   echo "</age>";
   echo "<sex>";
    echo "女";
   echo "</sex>";
echo "</user>";
echo "</users>";
?>
2：
<?php
header("Content-type: text/xml");
echo "<?xml version="1.0" encoding="UTF-8"?>";
echo "<users><user><name> 小小菜鸟</name><age>24</age><sex>男</sex>< /user><user><name>艳艳</name><age>23< /age><sex>女</sex></user></users>";
?>
3：
<?php

header('Content-Type: text/xml;');
//创建新的xml文件
$dom = new DOMDocument('1.0', 'utf-8');

//建立<response>元素
$response = $dom->createElement_x_x_x('response');
$dom->a($response);

//建立<books>元素并将其作为<response>的子元素
$books = $dom->createElement_x_x_x('books');
$response->a($books);

//为book创建标题
$title = $dom->createElement_x_x_x('title');
$titleText = $dom->createTextNode('PHP与AJAX');
$title->a($titleText);

//为book创建isbn元素
$isbn = $dom->createElement_x_x_x('isbn');
$isbnText = $dom->createTextNode('1-21258986');
$isbn->a($isbnText);

//创建book元素
$book = $dom->createElement_x_x_x('book');
$book->a($title);
$book->a($isbn);

//将<book>作为<books>子元素
$books->a($book);

//在一字符串变量中建立XML结构
$xmlString = $dom->saveXML();

//输出XML字符串
echo $xmlString;

?>

  ' + pre[2] + '    '); } if(post[0]){ document.write('下一篇<<  ' + post[2] + ''); } document.write('

'); }

1.php输出xml的实例

header('Content-Type: text/xml');
$sql = "select * from article order by post_date limit 100";
$re = $db->query($sql);
echo "<?xml version="1.0" encoding="utf-8"?>\n";
echo "<data>\n";
while($row = $db->fetchArray($re)){
echo "<event ";
echo "start="".strftime ("%b %d %Y %H:%M:%S", $row['post_date'])."" ";
echo "title="".htmlspecialchars($row['title'])."" ";
echo "link="tdetail.php?id=".$row['time_point'].""";
echo ">";
echo htmlspecialchars($row['content']);
echo "</event>\n";
}
echo "</data>";

2.用JavaScript操作XML 实例

文中尽量用上所有的操作和属性，以做示范

<script language="JavaScript">
<!--
var doc = new ActiveXObject("Msxml2.DOMDocument"); //ie5.5+,CreateObject("Microsoft.XMLDOM")

//加载文档
//doc.load("b.xml");
//创建文件头
var p = doc.createProcessingInstruction("xml","version='1.0'   encoding='gb2312'");
//添加文件头
doc.a(p);
//用于直接加载时获得根接点
//var root = doc.documentElement;
//两种方式创建根接点
// var root = doc.createElement_x_x_x("students");
var root = doc.createNode(1,"students","");
//创建子接点
var n = doc.createNode(1,"ttyp","");
       //指定子接点文本
       //n.text = " this is a test";

//创建孙接点
var o = doc.createElement_x_x_x("sex");
       o.text = "男"; //指定其文本
//创建属性
var r = doc.createAttribute("id");
       r.value="test";
       //添加属性
       n.setAttributeNode(r);
//创建第二个属性
var r1 = doc.createAttribute("class");
       r1.value="tt";
      
       //添加属性
       n.setAttributeNode(r1);
       //删除第二个属性
       n.removeAttribute("class");
       //添加孙接点
       n.a(o);
       //添加文本接点
       n.a(doc.createTextNode("this is a text node."));
       //添加注释
       n.a(doc.createComment("this is a comment\n"));

       //添加子接点
       root.a(n);

//复制接点
var m = n.cloneNode(true);
       root.a(m);
      
       //删除接点
       root.removeChild(root.childNodes(0));
//创建数据段
var c = doc.createCDATASection("this is a cdata");
       c.text = "hi,cdata";
       //添加数据段
       root.a(c);

//添加根接点
doc.a(root);
//查找接点
var a = doc.getElementsByTagName_r("ttyp");
//var a = doc.selectNodes("//ttyp");
//显示改接点的属性
for(var i= 0;i<a.length;i++)
{
       alert(a.xml);
       for(var j=0;j<a.attributes.length;j++)
       {
         alert(a.attributes[j].name);
       }
}
//修改节点,利用XPATH定位节点
var b = doc.selectSingleNode("//ttyp/sex");
b.text = "女";
//alert(doc.xml);
//XML保存（需要在服务端，客户端用FSO）
//doc.save();

//查看根接点XML
if(n)
{
       alert(n.ownerDocument.xml);
}
