PHP输出XML格式数据的方法总结

这篇文章主要介绍了PHP输出XML格式数据的方法,结合实例形式总结分析了php常用的xml格式数据输出相关操作技巧,需要的朋友可以参考下

本文实例讲述了PHP输出XML格式数据的方法。分享给大家供大家参考，具体如下：

方法1：

<?phpheader("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>";?>

上述示例运行效果图如下：

方法2：

<?phpheader("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>";?>

方法3：

<?phpheader('Content-Type: text/xml;');//创建新的xml文件$dom = new DOMDocument('1.0', 'utf-8');//建立<response>元素$response = $dom->createElement('response');$dom->a($response);//建立<books>元素并将其作为<response>的子元素$book<i>·本2文来源gaodai$ma#com搞$代*码网2</i><strong>搞gaodaima代码</strong>s = $dom->createElement('books');$response->a($books);//为book创建标题$title = $dom->createElement('title');$titleText = $dom->createTextNode('PHP与AJAX');$title->a($titleText);//为book创建isbn元素$isbn = $dom->createElement('isbn');$isbnText = $dom->createTextNode('1-21258986');$isbn->a($isbnText);//创建book元素$book = $dom->createElement('book');$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;?>

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("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XMLif(n){    alert(n.ownerDocument.xml);}//--></script>
