simplexml對象和對方陣列

Question

我有一個簡單的xml腳本，它創建了一個複雜的對象，我只想從div'grid'中獲取信息，所以抓住我使用xpath來獲取它。

$id = $sxml->xpath("//*[@id='grid_data']"); 

這會導致大的對象數組，這似乎是對象和數組的混合，我真的很努力地穿過它。下面是一個非常簡化的版本。有30個成員'人1'等。每個人都有一個列表，其中包含25個項目，我需要訪問/工作。 （[「li」] => array（25））

理想情況下，我需要遍歷每個成員，然後循環遍歷每個li項目，但即時通訊使用$ variable ['name'] vs $ object-> name

只是測試我嘗試了各種方法來獲取人名，我想我困惑着自己試圖圍繞對象遍歷我的頭。

echo $id[0]->div[0][p][a]; 
echo $id[0]['div'][0]['p']['a']; 
echo $id->0->div

讓我們用simplexml與xpath一起，看在線低於

<?php 
$xml = simplexml_load_file('xml.xml'); 

// let's take all the divs that have the class "stff_grid" 
$divs = $xml->xpath("//*[@class='stff_grid']"); 

// for each of these elements, let's print out the value inside the first p tag 
foreach($divs as $div){ 
    print $div->p->a . PHP_EOL; 

    // now for each li tag let's print out the contents inside the a tag 
    foreach ($div->ul->li as $row){ 
     print " - " . $row->a . PHP_EOL; 
    } 
} 
/* this outputs the following 
Person 1 
    - 1 hr 
    - 2 hr 
    - 3 hr 
    - 4 hr 
    - 5 hr 
    - 6 hr 
    - 7 hr 
    - 8 hr 
Person 2
