本文关键字：节点属性更新 php | 更新日期: 2023-09-27

嗨，我需要使用php从现有的xml内容中修改xml现有的xml

<?xml version="1.0" encoding="utf-8"?>
<Book  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" BookId="10010">
     <STRING id="Name" >Test1</STRING>
    <STRING id="ISBN">102399</STRING>
</Book>

新的xml

<?xml version="1.0" encoding="utf-8"?>
<Book BookId="10010" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
     <STRING id="Name" >XYZ</STRING>
    <STRING id="ISBN">7777</STRING>
</Book>

注意：BookID应该放在xmlns属性之前

提前谢谢。

使用SimpleXML:

$xml = simplexml_load_file($yourXMLPath);
//Loop for element...
foreach ($xml->STRING as $string) {
    //Update value for <STRING id="Name">...
    if($string->attributes()->id == 'Name'){
        $xml->STRING = 'XYZ';
    }
    //Update value for <STRING id="Name">...
    if($string->attributes()->id == 'ISBN'){
        $xml->STRING = '7777';
    }
}
// save the updated document
$xml->asXML('newXML.xml');
