The examples in this article describe PHP method to output data in XML format. Share it with everyone for your reference, the details are as follows:

Method 1:

<?php
header("Content-type: text/xml");
echo "<?xml version=&#39;1.0&#39; encoding=&#39;UTF-8&#39;?>";

header("Content-type: text/xml");
echo "<?xml version=&#39;1.0&#39; encoding=&#39;UTF-8&#39;?>";
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>";
?>

Method 3:

<?php
header(&#39;Content-Type: text/xml;&#39;);
//创建新的xml文件
$dom = new DOMDocument(&#39;1.0&#39;, &#39;utf-8&#39;);
//建立<response>元素
$response = $dom->createElement(&#39;response&#39;);
$dom->a($response);
//建立<books>元素并将其作为<response>的子元素
$books = $dom->createElement(&#39;books&#39;);
$response->a($books);
//为book创建标题
$title = $dom->createElement(&#39;title&#39;);
$titleText = $dom->createTextNode(&#39;PHP与AJAX&#39;);
$title->a($titleText);
//为book创建isbn元素
$isbn = $dom->createElement(&#39;isbn&#39;);
$isbnText = $dom->createTextNode(&#39;1-21258986&#39;);
$isbn->a($isbnText);
//创建book元素
$book = $dom->createElement(&#39;book&#39;);
$book->a($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;
?>

1.Example of php outputting xml

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", $row[&#39;post_date&#39;])."" ";
echo "title="".htmlspecialchars($row[&#39;title&#39;])."" ";
echo "link="tdetail.php?id=".$row[&#39;time_point&#39;].""";
echo ">";
echo htmlspecialchars($row[&#39;content&#39;]);
echo "</event>\n";
}
echo "</data>";

2.Example of using JavaScript to operate XML

Use all operations in the article as much as possible and attributes, as a demonstration

<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=&#39;1.0&#39;  encoding=&#39;gb2312&#39;");
//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("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("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);
}
//-->
</script>
