xml 노드 속성을 수정하고 추가하기 위한 PHP 구현 코드

참고용으로 XML 노드 속성 코드를 추가하도록 PHP가 수정되었습니다.
php는 xml 노드 속성을 수정하고 xml 노드 속성에 대한 코드를 추가합니다. 필요한 친구가 참조할 수 있습니다.

1. xml 파일

<?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 코드

<?
$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;);
?>

PHP는 XML 문서 속성을 구문 분석하고

<?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;); 
?>

그 당시 xml 문서:

<?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>

//다음 파일은 수정되었으며 수정 가능 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;); 
} 
} 
} 
}  
?>
