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');

}

}

}

}

?>
