php 修改 增加xml结点属性的代码，供大家学习参考。
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="1935" /> <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="5" autoPlay="false"> <item name="Birthday" src="cartoon/movie/birthday.swf" thumb="cartoon/preview/birthday-small.swf" duration="15"/> <item name="Boom" src="cartoon/movie/boom.swf" thumb="cartoon/preview/boom-small.swf" duration="6"/> <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="13"/> <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(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 ":"; // 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‘,‘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>
//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‘); } } } } ?>
