'; }否则{ 退出（'打开Sample.xml失败'）； } 我得到的结果是

$xml=simplexml_load_string($yourXMLFile)
$xml->children('g', true)->id;

我必须将项目的数据存储在特定的变量中。

我相信使用这种xml样式，您可以使用标准的PHP xml解析器（即将其加载到变量中（即$xml）然后像这样读取这些节点：

<?php
ini_set('display_errors', 1);
$object= new DOMDocument();
$object->loadXML('<?xml version="1.0" encoding="utf-8" ?>

您可以使用

PHP

DOMDocument

来完成它。正如我在下面的代码中所做的那样

getElementsByTagName（“项目”）作为$item）
{
foreach（$item->childNodes作为$node）
{
if（$DOMELENT的节点实例）
{
if（在数组中（$node->tagName，$tagValues））
{
$result[$node->tagName][]=$node->textContent；
}
}
}
}
打印（结果）；

试试这个，测试过了

array(1) {
    ["g"]=> string(29) "http://base.google.com/ns/1.0"
}

输出：

foreach ($xml->channel->item as $item) 
{ 
    // for php >= 5.2.0
    // $id = (string) $item->children('g', TRUE)->id; 
    // for php < 5.2.0
    // $id = (string) $item->children('http://base.google.com/ns/1.0')->id; 
    $id = (string) $item->children($namespaces["g"])->id; // for php < 5.2.0
    $title = (string) $item->title; 
    $link  = (string) $item->link; 
    var_dump($id, $title, $link); 
    echo "--\n"; 
}

$xml = simplexml_load_file('http://example.com/rss.xml');
$namespaces = $xml->getNamespaces(true);
$itemArray = array();
foreach ($xml->channel->item as $item) 
{ 
    $obj = new stdClass();
    $obj->id = (string) $item->children($namespaces["g"])->id; // for php < 5.2.0
    $obj->title = (string) $item->title; 
    $obj->link  = (string) $item->link; 
    $itemArray[] = $obj;
} 
var_dump($itemArray);

$handle_object = $element->children('g', true);

然后：

最后，例如，为了将结果绑定到对象数组：

array(2) {
    [0]=> object(stdClass)#5 (3) {
        ["id"]=> string(12) "ACKKALID0577"
        ["title"]=> string(8) "Kalidasa"
        ["link"]=> string(58) "http://www.amarchitrakatha.com/in/kalidasa?fee=19&fep=1147"

    [1]=> object(stdClass)#3 (3) {
