Question

我试图让所有类别并将其推入我的array解析DOM文档，到目前为止我做这种方式，我的xml每个项目有几个类别。什么是这样做的好方法？

<item> 
    <title>Submit</title> 
    <category>Foo</category> 
    <category>Bar</category> 
</item> 

感谢

Answer 1

这应有助于：

$doc = new DOMDocument(); 
$doc->load('myxml.xml'); 
$arr = array(); 
foreach ($doc->getElementsByTagName('item') as $node) { 
    $item = array ( 
     'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 
     'date' => array() 
    ); 

    foreach($node->getElementsByTagName('category') as $catNode) 
    { 
     $item['date'][] = $catNode->nodeValue; 
    } 

    $arr[] = $item; 
}

您需要嵌套的循环：

$doc = new DOMDocument(); 
$doc->load('myxml.xml'); 
$arr = array(); 

foreach ($doc->getElementsByTagName('item') as $itemNode) { 
    $items = array( 
     'title' => $itemNode->getElementsByTagName('title')->item(0)->nodeValue, 
     'date' => array() 
    ); 

    foreach ($itemNode->getElementsByTagName('category') as $categoryNode) { 
     $items['date'][] = $categoryNode->nodeValue; 
    } 

    $arr[] = $items; 
}
