我有以下格式的xml文件。如何用Php读取XML文件数据？

通过使用simplexml_load_file我没有收到项目的数据。如何用PHP解析这种格式的XML？我想喜欢G的所有项目的数据：ID，标题，链接等

if (file_exists('Sample.xml')) { 
$xml = simplexml_load_file('Sample.xml'); 
echo '<pre>'; 
print_r($xml->channel); 
echo '</pre>'; 
} else { 
exit('Failed to open Sample.xml.'); 
}

和M得到的结果

SimpleXMLElement Object 
(
[title] => Data feed Title 
[link] => http://www.amarchitrakatha.com/in/ 
[description] => Data feed description. 
[item] => Array 
    (
     [0] => ACKKALID0577 

     [1] => ACKPRITH1413 
    ) 
)

我必须存储在特定变量的数据项。

什么是您的PHP版本？ – kolunar

你已经包含了你的XML，但不包括你想用来导入它的代码。你能否包括你的代码，以及更精确的结果描述？ “没有获得项目的数据”可能是许多事情中的任何一个。检查你的错误日志，包括任何可疑[在你的问题]（http：// stackoverflow。COM /职位/ 43464051 /编辑）。当你处于这个状态时，你可能想要包含一个更完整的描述你想要对结果做什么;最好的方向通常是通过了解你的目的地来确定的。 :) – ghoti

我相信这个XML风格，你可以使用标准的PHP的XML解析器（即http://ca2.php.net/manual/en/class.simplexmlelement.php） 加载到您的变量（即$ XML） 然后阅读这些节点就像这样：

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

（中上面会拉所有的实例< g：id >）

未测试我的结局。

您可以使用PHPDOMDocument来完成它。正如我在下面的代码中所做的那样。

Try this code snippet here

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

它给出了结果，但我必须将数据存储在特定变量中。 – Magecode

@Cvince好的没有问题我正在更新我的文章，在几秒钟内 –

@Cvince现在检查我的帖子，看看'尝试这段代码片段'你可以在那里检查，你也可以使用'extract'。 –

试试这个，测试了！

$xml = simplexml_load_file('http://example.com/rss.xml'); 
$namespaces = $xml->getNamespaces(true); 
var_dump($namespaces);

输出：

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

然后：

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"; 
}

输出：

string(12) "ACKKALID0577" 
string(8) "Kalidasa" 
string(58) "http://www.amarchitrakatha.com/in/kalidasa?fee=19&fep=1147" 
-- 
string(12) "ACKPRITH1413" 
string(18) "Prithviraj Chauhan" 
string(68) "http://www.amarchitrakatha.com/in/prithviraj-chauhan?fee=19&fep=1150" 
--

最后，对于例如以将结果结合对象的数组：

$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);

输出：

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) { 
     ["id"]=> string(12) "ACKPRITH1413" 
     ["title"]=> string(18) "Prithviraj Chauhan" 
     ["link"]=> string(68) "http://www.amarchitrakatha.com/in/prithviraj-chauhan?fee=19&fep=1150" 
    } 
}

你可以得到g中的值：使用此属性

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