xml文件:
<?xml version="1.0" encoding="UTF-8" ?>
<clientSet>
<server url="192.168.0.180" port="1935" />
<rootPath value="" />
<homePath value="ht.com" />

</clientSet>
php代码:
<?
$dom=new DOMDocument('1.0');
$dom->load('x.xml');
$em=$dom->getElementsByTagName('emotions');
$em=$em->item(0);
$items=$em->getElementsByTagName('item');
foreach($items as $a){
foreach($a->attributes as $b){
if($b->nodeValue=='Birthday'){
$a->setAttribute('name','nBirthday');
}
}
}
$t=$dom->createElement('item');
$t->setAttribute('name','x');
$t->setAttribute('src','www.baidu.com');
$t->setAttribute('ration','ration');
$em->appendChild($t);
$dom->save('x.xml');
?>
PHP解析XML文档属性并编辑:
<?php
//读取xml
$dom=new DOMDocument('1.0');
$dom->load('data.xml');
$em=$dom->getElementsByTagName('videos');//最外层节点
$em=$em->item(0);
$items=$em->getElementsByTagName('video');//节点
//如果不用读取直接添加的话把下面这一段去掉即可
foreach($items as $a){
foreach($a->attributes as $b){//$b->nodeValue;节点属性的值$b->nodeName;节点属性的名称
echo $b->nodeName;
echo ":";
echo $b->nodeValue;
echo "<br/>";
}
}
//下面是往xml写入一行新的
$t=$dom->createElement('video');//<video
$t->setAttribute('title','1');//<video name="data"
$t->setAttribute('src','2');//<video name="data" src="2"
$t->setAttribute('img','1');//<video name="data" img="1"
$em->appendChild($t);//<video name="data" img="1"/>
$dom->save('data.xml');
?>
当时的xml文档:
<?xml version="1.0"?>
<videos>
<video img="a" url="1" title="1" nickname="1" tag="1" vid="1" star="1"/>
<video img="b" url="2" title="2" nickname="2" tag="2" vid="2" star="2"/>
<video img="c" url="3" title="3" nickname="3" tag="3" vid="3" star="3"/>
<video title="d" src="2" img="1"/>
</videos>
//下面这一个文件是后改的可以修改xml:
<?php
$doc = new DOMDocument();
$doc->load('data.xml');
//查找 videos 节点
$root = $doc->getElementsByTagName('videos');
//第一个 videos 节点
$root = $root->item(0);
//查找 videos 节点下的 video 节点
$userid = $root->getElementsByTagName('video');
//遍历所有 video 节点
foreach ($userid as $rootdata)
{
//遍历每一个 video 节点所有属性
foreach ($rootdata->attributes as $attrib)
{
$attribName = $attrib->nodeName; //nodeName为属性名称
$attribValue = $attrib->nodeValue; //nodeValue为属性内容
//查找属性名称为ip的节点内容
if ($attribName =='img')
{
//查找属性内容为ip的节点内容
if ($attribValue =='1')
{
//将属性为img,img内容为1的修改为image;
$rootdata->setAttribute('img','image');
$doc->save('data.xml');
}
}
}
}
?>

PHP SimpleXML 函数在向你招手:
