php 修改、增加xml结点属性的实现代码

1、xml文件

<?xml version="1.0" encoding="UTF-8" ?>  <clientSet>  <server url="192.168.0.180" port="1935" />  <rootPath value="" />  <homePath value="http://www.aaa.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 ":";    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');   }   }   }   }    ?>
