php修改xml结点属性，增加xml结点属性的代码，有需要的朋友，参考下。

1、xml文件

复制代码代码如下:

<?xml version="1.0" encoding="UTF-8" ?>
<clientSet>
<server url="192.168.0.180" port="" />
<rootPath value="" />
<homePath value="http://www.jbxue.com" />
<helpPath value="help.html" />
<language value="en" />
<theme value="default" />
<visibleMarquee value = "true" />
<visibleWhitePaper value="true" />
<showMemberRoomForGuest value = "true" />
<emotions enabled="true" column="" autoPlay="false">
<item name="Birthday" src="cartoon/movie/birthday.swf" thumb="cartoon/preview/birthday-small.swf" duration=""/>
<item name="Boom" src="cartoon/movie/boom.swf" thumb="cartoon/preview/boom-small.swf" duration=""/>
<item name="Bubble" src="cartoon/movie/bubble.swf" thumb="cartoon/preview/bubble-small.swf" duration="7.5"/>
<item name="Cry" src="cartoon/movie/cry.swf" thumb="cartoon/preview/cry-small.swf" duration="5.4"/>
<item name="Doggie" src="cartoon/movie/doggie.swf" thumb="cartoon/preview/doggie-small.swf" duration=""/>
<item name="Greeting" src="cartoon/movie/greeting.swf" thumb="cartoon/preview/greeting-small.swf" duration="7.4"/>
<item name="Football" src="cartoon/movie/football.swf" thumb="cartoon/preview/football-small.swf" duration="2.2"/>
</emotions >
</clientSet>

2、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('duration','duration');
$em->appendChild($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();
$items=$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 ":"; // www.jbxue.com
echo $b->nodeValue;
echo "<br/>";
}
}
//下面是往xml写入一行新的
$t=$dom->createElement('video');//<video
$t->setAttribute('title','');//<video name="data"
$t->setAttribute('src','');//<video name="data" src="2"
$t->setAttribute('img','');//<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>

//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(); //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 =='')
{
//将属性为img，img内容为1的修改为image;
$rootdata->setAttribute('img','image');
$doc->save('data.xml');
}
}
}
}
?>
