php modifies xml node attributes and adds the code for xml node attributes. Friends in need can refer to it.

1.xml file

<?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="Football" src="cartoon/movie/football.swf" thumb="cartoon/preview/football-small.swf" duration="2.2"/>
</emotions >
</clientSet>

2.php code

<?
$dom=new DOMDocument(&#39;1.0&#39;);
$dom->load(&#39;x.xml&#39;);
$em=$dom->getElementsByTagName(&#39;emotions&#39;);
$em=$em->item(0);
$items=$em->getElementsByTagName(&#39;item&#39;);
foreach($items as $a){
foreach($a->attributes as $b){
if($b->nodeValue==&#39;Birthday&#39;){
$a->setAttribute(&#39;name&#39;,&#39;nBirthday&#39;);
}
}
}
$t=$dom->createElement(&#39;item&#39;);
$t->setAttribute(&#39;name&#39;,&#39;x&#39;);
$t->setAttribute(&#39;src&#39;,&#39;www.baidu.com&#39;);
$t->setAttribute(&#39;duration&#39;,&#39;duration&#39;);
$em->appendChild($t);
$dom->save(&#39;x.xml&#39;);
?>

PHP parses the XML document attributes and edits

<?php
//读取xml
 $dom=new DOMDocument(&#39;1.0&#39;);
$dom->load(&#39;data.xml&#39;);
$em=$dom->getElementsByTagName(&#39;videos&#39;);//最外层节点
$em=$em->item(0);
$items=$em->getElementsByTagName(&#39;video&#39;);//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(&#39;video&#39;);//<video
$t->setAttribute(&#39;title&#39;,&#39;1&#39;);//<video name="data"
$t->setAttribute(&#39;src&#39;,&#39;2&#39;);//<video name="data" src="2"
$t->setAttribute(&#39;img&#39;,&#39;1&#39;);//<video name="data" img="1"
$em->appendChild($t);//<video name="data" img="1"/>
$dom->save(&#39;data.xml&#39;);
?>

The xml document at that time:

<?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>

//The following file was modified later and can be modified xml

<?php
$doc = new DOMDocument();
$doc->load(&#39;data.xml&#39;);

//查找 videos 节点
$root = $doc->getElementsByTagName(&#39;videos&#39;);

//第一个 videos 节点
$root = $root->item(0);

//查找 videos 节点下的 video 节点
$userid = $root->getElementsByTagName(&#39;video&#39;);

//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 ($attribName ==&#39;img&#39;)
{
//查找属性内容为ip的节点内容
if ($attribValue ==&#39;1&#39;)
{
//将属性为img，img内容为1的修改为image;
$rootdata->setAttribute(&#39;img&#39;,&#39;image&#39;);
$doc->save(&#39;data.xml&#39;);
}
}
}
}
?>
