PHP生成XML的方法很多,这里演示最基本,最简单的字符串构造法。就是使用字符串构造或者拼接成xml数据格式,然后输出或者生成xml文件。
<?php
$data = array(
array(
'title' => 'baidu',
'country' => 'china',
'name' => '百度',
),
array(
'title' => 'google',
'country' => 'usa',
'name' => '谷歌',
)
);
//构造xml数据格式
$xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";
$xml .= "<data>\n";
foreach ($data as $itm) {
//循环构造xml单项
$item = "<item>\n";
$item .= "<title>" . $itm['title'] . "</title>\n";
$item .= "<country>" . $itm['country'] . "</country>\n";
$item .= " <name>" . $itm['name'] . "</name>\n";
$item .= "</item>\n";
$xml .=$item;
}
$xml .= "</data>\n";
//输出xml数据
echo $xml;
?>
生成的数据格式如下:

$obj = simplexml_load_string($str);
echo $content=$obj->params->param->value->string;
不得不说,非明就是一个标准的xml,为什么非得用正则?你觉得php的正则很快么?
preg_match('/\<string\>\(.*)<\/string\>/',$str,$arr);
echo $arr[1];
echo $content=$obj->params->param->value->string;
不得不说,非明就是一个标准的xml,为什么非得用正则?你觉得php的正则很快么?
preg_match('/\<string\>\(.*)<\/string\>/',$str,$arr);
echo $arr[1];
追问
为什么我本地要这么写才能正确返回结果了?
preg_match('/\(.*)/',$str,$arr);
echo $arr[1];
用正则是因为这个东西返回来的结果不是规定的,有时候返回的不是标准的xml,所以我觉得最好还是用正规则来获取。
追答
说明我写的那段正则有转义没转对呗!
完整的正则应该加前面的一堆,
....balabala
最好还是找一下xml标签的正则...

其中a为append Child
1:
<?php

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);
